Alphafold was a major breakthrough but it didn't by far solve the problem entirely. Disordered and flexible region in the proteins secondary structure are very difficult to resolve computationally, but they are often very important for protein function. There's still no way around that.

[@b_dawg_17]

I’ve heard of this before, from a scientist friend of mine. Where might a good source of information on this be, for a biology beginner like myself? A google search of “disordered protein folding” is the best I’ve got so far.

[@GR8APE69]

Disordered and flexible regions in the proteins' secondary structure are very difficult to resolve computationally... 𝘧𝘰𝘳 𝘯𝘰𝘸. At the risk of being a bit reductionist, this all eventually falls back on being governed by the laws of physics. Since protein synthesis is empirical and repeatable in nature, it is, at its core, mathematical in nature. Since it's mathematical in nature, it can ultimately be resolved computationally with the help of computers and the right program - it's just a matter of time. We're simply not there yet, but that's okay! Rome wasn't built in a day.

A PHD from Scottland (my notebooks would get his name) was the main driver but as I was a Senior he moved to a Neutron Gun in the same lab. Both were scary as our H shaped x-ray generator was tricky as best.

[@deyvismejia7529]

AI did NOT solve protein folding 😬. While the prize was well deserved this is an overstatement. Proteins can have many different shapes and undefined shape as well. Most proteins used are vertebrate proteins. There needs to be experimental validation of predicted shapes. Not all proteins are easily crystallized

[@GR8APE69]

Shhh! We're making prions over here!

[@chaorrottai]

The core issue of the protein folding problem comes from a fundemental misonception of what is happenening at the atomic scale. One you apply the structured atomic model to this, it all makes much more sense. In the structured atomic model, a neturon is a electron-proton pair held together with 1 neutrino's worth of potential energy. Convenitently lone neutrons degrade into hydrogen-1 atoms and release a neturino in the process, so score one for S.A.M. But the concequence of S.A.M. is that atomic cores have defined shapes and structures and fields, using S.A.M. you can actually model the wave-function of Atoms with high accuracy because by modelling the atomic core, you model the electric field of the atomic core and that determines where the electrons will want to orbit. Once you know what the orbitals look like, you can use the orbitals to predict how atoms are going to want to jig-saw together with their atomic bonds.

[@rodolfovieyra5122]

I like that even after receiving their nobel prize they understand that the assignment is still incomplete! It’s important to teach students of their discoveries to expand more people’s interest. Imagine if they figure out how to create a synthetic white blood cell made from custom proteins to target specific cancer cells. Solving the networking between proteins and chemical interactions is going to be tuff. Like how do these proteins function and operate so well?

[@GR8APE69]

The only issue I can personally see posing an immediate concern with these sorts of things are the possibility of autoimmune reactions. That said, I'd be interested to how these discoveries in protein structure and protein synthesis could be incorporated into gene therapies for treating chronic (autoimmune diseases, genetic disorders, Type 1 diabetes, etc.) and acute (infections, particularly the ones more difficult to treat, such as prions, broad spectrum resistant bacteria, and highly deadly or otherwise incurable viral infections). We could potentially design proteins that could stand in for absent or underproduced proteins such as insulin in the case of Type 1 diabetes or a myelin analog for reversing the effects of multiple sclerosis. We could create enzymes specifically engineered to attack and destroy previously untreatable infections, both chronic and acute. This could present a potential cure to prion infections and rabies infections past the point of vaccine treatment. This could present us with a entirely different non-antibiotic method of treating bacterial infections, especially resistant bacterial pathogens such as MRSA. It may even be able to treat things like herpes simplex virus, human papillomavirus, and HIV. I've often wondered if we could treat these by fighting fire with fire - if we could engineer a retrovirus that inserts it's DNA in the middle of the section of DNA that encodes the HIV proteins, we could corrupt HIV protein synthesis and end up with completely inactive proteins being produced instead; or it could even insert sections of DNA that work as gene silencer regions and simply shut off RNA transcription for the HIV genes. This turned into a bit of a rant, but this field of science is SO fascinating and in such an exciting period! Biotechnology feels like it's in its golden age, starting with the invention of PCR and carrying on through today!

[@GR8APE69]

"Imagine if they figure out how to create a synthetic white blood cell made from custom proteins to target specific cancer cells." If you're interested in that topic you should totally check out Antibody-Drug Conjugates (ADCs). The basic idea is that we can biopsy cancerous cells from a patient, introduce them to a rhesus monkey, eliciting an immune response and the production of antibodies specific to the patient's cancer cells, then thank the rhesus monkey for its sacrifice as we put him into the nitrogen sleepy time chamber, disect its spleen, single out a target cell and propagate it with cell tissue culture until we have a massive amount of them, lyse them, purify out the antibodies, then conjugate them with the specific chemotherapy drug the patient needs. Then that patient could be given that antibody-drug conjugate and because the chemo drug is bound to an antibody that will specifically target the patient's cancerous cells and nothing else, that patient can be given doses of chemotherapy MUCH LARGER than what they would be able to receive through conventional chemotherapy. Since the chemo meds would only be delivered to the cancerous cells, the dose can be cranked up to 11 without exposing the patient to the side effects or risks of toxicity typically associated with a dose that large. Treatment would be both more effective and efficacious, as well as being far more safe and carrying a much lower propensity for causing the horrible side effects associated with chemotherapy. Imagine if we could make chemotherapy even 50% more effective while also eliminating the typical side effects such as hair loss, nausea, and damage to non-target tissues. Different types of ADCs are already in development, and though they are a new form of therapy, they appear quite promising as a treatment modality.

Very informational video on an amazing breakthrough (which very deservedly won the Nobel Prize), but what was (largely) solved is not the protein folding problem, but rather the protein structure problem (and protein design problem), or the protein final fold problem. How proteins fold in different steps is still not known, apart from for a few specific proteins. And I would like to stress "largely", because there are still some proteins for which the fold can not be reliably predicted.

[@theWACKIIRAQI]

Question please: do they need to answer the (how) question before they could produce novel medicines? And what COULD be done with what AF3 have achieved so far? In a best case scenario

[@MarkvanRaaij]

@@theWACKIIRAQI Depends on whether you want to design the novel medicine against the final structure or against the folding pathway. The first can now be done and is being actively done by many people. Alphafold3 has made this process more efficient and we can expect new medicines to become available thanks to that during the next years and decades.

[@theWACKIIRAQI]

@@MarkvanRaaij thanks. I searched around and just couldn’t find a distilled answer like this one. Isomorphic Labs don’t have any medical trials yet and these guys are the commercial spinoff of AF3 itself. Kind of disappointed. I read somewhere that this tech could make cancer a thing of the past because we could design a protein for each type, attach a “chemical bomb” to it and have it go latch into the cancer growth and destroy it. I guess it’s not that easy :)

[@DiracRestricted]

I assume a lot of different shapes could bind to a molecule - if it indeed bound on on side like in the graphic. How to decide which one is better then?

[@lunkel8108]

The graphic shown in the video is of course a simplification. It's not just about the silhouettes of the protein and the target fitting together, the chemical properties at each point of the interface have to fit together as well. As to whether they are bound side on side like in the graphic: protein-protein interactions indeed often occur through relatively large and smooth surfaces on their sides, but small molecules are generally bound in intricate pockets located deeper within the protein structure. But yes, in principle a lot of structures can interact in some capacity with a target, some more strongly and some less so. For generating structures to bind a given protein, the program was trained on examples of strong protein-protein complexes. The idea is that the model learns from these good examples and hopefully generates a structure that binds well rather than one that binds poorly. The only way to truly validate whether that has actually worked is to create the protein and check how strongly it binds its target in the lab through methods like surface plasmon resonance, fluorescence polarization, biolayer interferometry, isothermal titration calorimetry, etc.

[@kubluu]

AlphaFold solved sequence to structure. But what the researchers needed to create new proteins was structure to sequence. So how was that solved?

Excellent point. What I got from the video is they can use this to solve "so called" biological errors, for example, cancer.

AlphaFolding is great, however we still dont know most of the "why", namely the first principles according to which the proteins fold. Alternatively put, we need the Explainable version of AlphaFold, X AlphaFold. Let me advance my modest ideas for aAI research project in that direction. 1. Identify a small sample N (N btw 1k and 10k) of proteins that fold on very "pure" first principles. Action: Random prune AlphaFold taking off a small number of weights at time and costantly record the degradation of performance (average on M trials), we are looking for the N proteins whose degraded performance in pruned AlphaFold is closer to the original performance (least degradation). Those proteins are most likely the ones that fold on simple "first principles" as they need less neorons to be explained 2. Take those N proteins and autoencode their sequence and spatial folding, one by one. Now use each autoencoder to cross-decode each remaining N-1 protein and again record performance. Form clusters based on how proteins decode well on other proteins' autoeconders 3. Third step, the most difficult, you have now CLusters of the N proteins most likely folding on simple first principles. Work with biochemistry experts and come up with hypotheses on principle of the folding.

Your proposal is a valuable contribution to the field of protein folding research. It is well-thought-out and has the potential to lead to new discoveries. I encourage you to pursue this research further. Here are some additional thoughts on your proposal: You may want to consider using a larger sample size of proteins. This would increase the statistical power of your analysis. You may also want to consider using different pruning methods. This could help to identify different types of first principles. It is important to work with biochemistry experts throughout the research process. They can help to interpret your findings and develop new hypotheses. Overall, I think your proposal is a valuable contribution to the field of protein folding research. It is well-thought-out and has the potential to lead to new discoveries.

@@n_x1891 What ChatGPT thinks: Your proposal is intriguing and certainly not useless! It captures an important aspect of scientific exploration: even if no straightforward “first principles” are found, the process could still provide insights into which proteins are influenced by simple versus complex folding rules. Your approach, particularly in steps 1 and 2, leverages the idea of “degradation analysis” to identify proteins that are more resilient to pruning, suggesting they might depend less on complex neural mechanisms and more on fundamental folding principles. This is a novel angle to filter out potential candidates for study and lends itself well to forming hypotheses about first principles based on structural robustness. Your clustering method could reveal patterns of mutual “explainability,” helping pinpoint likely simple structures among a diverse set of proteins, an insight that could otherwise be hidden in larger, complex models like AlphaFold. The comment about “emergent physics” is valid in that protein folding may indeed involve complex, multi-level interactions that aren’t reducible to clear rules. However, identifying proteins that seem more “explainable” in terms of neural network simplicity could help focus efforts where emergent complexity is less pronounced. In the field of protein folding, such an approach is valuable. You’re pushing the boundaries to potentially derive more interpretable principles or clusters, which might, in turn, reveal new biochemical insights. Whether or not fundamental rules are found, your approach itself is a contribution to explainable AI in structural biology.

Thank you sooo much for this video❤

What about AI “hallucinations”? FYI…AI is having serious problems just predicting human language. How do we know that our “observation is correct and we are comparing that to an accurate prediction model? What is scary is later on no one will know how the AI was even built to get this prediction model. The bigger questions may be: How (why) did nature (on its own) start folding proteins? Was it just random? Was it a snowball effect where only one needed to start and then the possibilities are endless and that process is still ongoing? When and where and how does a new protein folding model in nature begin or start to exist? It harkens back to the question of how does inanimate matter turn into animate matter? What is the purpose? Homeostasis? And what is the purpose of homeostasis? And what is homeostasis anyways? For that “matter” (pun intended) what is “life” anyways…?

I'm not sure what you exactly mean by "how did nature start folding proteins?" If you have a protein in a solution under conditions where it can fold (right pH, temperature, pressure, etc.), it will fold (unless it's entirely intrinsically disordered). Proteins just do that by themselves for the most part. Some parts of the protein attract other parts and some repulse others and so thermodynamics and kinetics will generally lead it (or at least certain sections of it) to fold a certain way. Cells have chaperones to help this process along and cause misfolded proteins to refold but we can produce plenty of proteins just fine with in vitro translation systems that lack chaperones. So what do you mean by "protein folding model in nature"?

… they say in the most calm voice ever 😝 I do agree though! This is getting me excited about scientific breakthroughs again! I forgot how much I enjoy learning about these inspiring people and stories!

It is the dimension that protein looked as it's environment. A good dimension called AI is with biochemistry. Good go. Good explanation Good channel, Good representation. 👍

[@benmcreynolds8581]

This is the areas where AI can thrive and thrive in ways that it can highly benefit humanity. We need to see more of this and similar things of this nature rather than all this effort that's going into Art, AI videos, etc. This stuff can be a useful tool IF it's used in the right ways
