Ron Vale (UCSF, HHMI) 2: Molecular Motor Proteins: The Mechanism of Dynein Motility

At 5:47 the good doc referred to melanocytes as a type of "skin" cell when in fact they are derived from neuroectoderm. That's right the cells that shade our skin eyes and hair are from a section of our outer embryonic layer that has already begun to infold into nerve tissue-the inception of our CNS. So the diseases that affect pigment also affect our nervous system where melanocytes function as well. So much for intelligent design!

So glad real scientists are doing real science. The more we learn about our amazing extremely complex purposeful intelligent design the harder it becomes for evolutionary scientists to explain how such immensely complex systems could evolve at all.

[@sorryplease5071]

Complexity is a result of evolution, not design. All of our examples of design always tend toward the simplest expression of function. The complexity comes out of the chaos, not careful intentional design. Creationism itself is extremely simplistic magical “god of the gaps” thinking that does absolutely nothing to further scientific knowledge and understanding of the natural world.

I only just randomly came across this stuff today. So based on my limited understanding, these motors can also be associated with diseases through mutations. This I believe opens up the possibility discovering what causes what is commonly defined as Dyskinetic Syndrome (loss of control over mobility, random mobility) in Tarantulas and other arachnids within the pet trade - which either ends up in a painful death for the animal, or "Mercy Euthanized" by the owner to end the animal's suffering - without ever there being a chance of recovery. If you were to find/locate a tarantula with DKS, it could become possible to: A: Identify what exactly is causing DKS B: Potentially come up with a mechanism which could help cure/treat arachnids and other animals suffering from such conditions. C: How would such a study and potential treatment be applied to non-humans?

[@Caoimhin28]

Very nice and very informative. Do we know which structure dynein or kinesin's move "faster"?? Are they differentially expressed in certain cellular components e.g. sperm axoneme? And does the difference in "speed" reflect the cellular function dependent on location of expression?? Since dynein is larger, I presume it takes bigger steps??? Thanks!

[@DanceSeek]

He didn't say, but comparing the descriptions of how the two motors function, I would think the kinesin moves faster, striding steadily forward with each step, while dynein takes a "two steps forward, one step back" approach.

This might just be evidence that our creation may not have been by chance, but by a being with higher technology. All these motors and their function do not appear to be a random occurrence, but more like a highly complex coordinated dance of ballet, tap, Jazz, waltz, hula, indeed countless more dances all together in a massively choreographed event that sugestests an even greater choreographer. If this is not evident to science, then they are not capable of rational thought.

[@vargon557]

Amazing discussion of how subcellular motors work. I'm impressed that what we have learned is still incomplete, even though our understanding has improved over the years. Myosin and kinesin were thought to be related, one being derived from the other by virtue of evolution, but now we know they're not related at all... It's amazing that all this complexity can be declared to be the result of evolution because the lecturer says so, and then he can change his mind and tell us something else. Life used to be so simple until we found out it isn't. All this molecular machinery that functions together so perfectly to perform vital tasks at the right time and in the right order gets more complicated every year as we find out more about what's involved. In case you haven't heard, Darwin is dead.

[@alexr2324]

First let me say beautiful presentation, and fascinating work. It took decades of research and study by highly intelligent people to reach this point and we still have no clue, how, why, what. May I suggest all the labs of the world couldn’t build a machine with a fraction of the complexity, and yet we’re told to believe this all happened and happens by chance and time. One of which does not exist as chance is not a force, and time which only produces death. After seeing this and continue to believe in evolution is to check your brain at the door. Again beautiful work, but there’s no evolution here.

[@borisjohnson1944]

Dear alexr2324, thing is, you have an agenda. The many scientists who do this work are expanding knowledge. You, on the other hand, seem to be complaining about the fact that these very smart people work very hard, day after day, year after year. Somehow you don't like that. Apparently, you have neither the intelligence nor the industry to work as they do. So, while they are busy working, you come along and presuppose that they all have some kind of "God issue" that demands your efforts to set things straight. In reality, the scientists are doing what intelligent people have always done: using their brains. I doubt that you spend much effort (on anything really) complaining about past scientists who developed the wheel, or the airplane, or the cell phone, or any of the other things we take for granted. Yet you seem very disturbed that God is not mentioned in every other breath. Otherwise, I suppose you would have to find some other way to make yourself superior to others. My condolences.

Dear @@itsReallyLou, As a young aspiring scientist myself and former evolutionist, I ended up as an electrical engineering, nevertheless I took many of the same classes scientists take on their way to organic chemistry and beyond. I know what the scientist say, I've read, listened and studied them for the last 35 years, I have seen nothing that explains the origins of life that makes any sense or can produce any result. But don't take my word for it, why don't we hear what Werner Karl Heisenberg the German Nobel Prize winning theoretical physicist and one of the key pioneers of quantum mechanics said about it... he said; "The first gulp from the glass of natural sciences will turn you into an atheist, but at the bottom of the glass, God is waiting for you."

[@platzhirsch4275]

The assembly of complex molecules involves a series of enzymes that must react in a proper sequence, very often producing intermediates that are useless to the cell until the final product is formed. Evolutionists imagine that these enzymes evolve randomly, often from a duplicate gene, and that the succession of steps in the synthesis, at least often, represents the succession of steps in the historical evolution of the process (the Granick hypothesis). But forces of natural selection could not operate to favour an organism which had ‘evolved’ a series of enzymes which merely produced useless intermediates until it somehow got around to making the end product. The Calvin cycle requires eleven different enzymes, all of which are coded by nuclear DNA and targeted precisely to the chloroplast, where the coding sequence is clipped off at just the right place by a nuclear-encoded protease. In reality, as described in the preceding paragraph, none of the enzymes can be missing if the Calvin cycle is to function. It is true that many of these enzymes are ubiquitous in living systems because every living cell needs to generate ribulose phosphates for the production of RNA, but evolutionists cannot solve the problem by merely pushing it back in time. The assembly of chlorophyll takes seventeen enzymes.21 Natural selection could not operate to favour a system with anything less than all seventeen being present and functioning. What evolutionary process could possibly produce complex sophisticated enzymes that generate nothing useful until the whole process is complete? Some evolutionists argue that the assumed primeval organic soup had many of the simpler chemicals, and that only as they were used up did it become necessary to generate the earlier enzymes in the pathway. In The Mystery of Life’s Origin: Reassessing Current Theories, the authors set forth the good basic chemistry that demonstrates that there could never have been an organic soup, and present some of the evidence out there in the world indicating that there never was.22 Denton23 and Overman24 also cite a number of experts who suggest that there is no evidence for such a primitive soup but rather considerable evidence against it. Chlorophyll itself, and many of the intermediates along its pathway of synthesis can form triplet states, which would destroy surrounding lipids by a free radical cascade apart from the context of the enzymes that manufacture them and the apoproteins into which they are inserted at the conclusion of their synthesis.25 According to Asada26 ‘triplet excited pigments are physiologically equivalent to the active oxygens’, and according to Sandmann and Scheer, chlorophyll triplets ‘are already highly toxic by themselves . . . .’27 The entire process of chlorophyll synthesis from δ-aminolevulinic acid to protoporphyrin IX is apparently tightly coupled to avoid leakage of intermediates.28 Almost all of the enzymes of chlorophyll biosynthesis are involved in handling phototoxic material.29 For many of these enzymes, if they are not there when their substrate is manufactured, the cell will be destroyed by their substrate on the loose in the wrong place at the wrong time. Apel30 has cited four of the enzymes of chlorophyll biosynthesis for which this has been proven to be the case. This is a significant problem for evolutionists, who need time for these enzymes to evolve successively. Each time a new enzyme evolved it would have produced a new phototoxin until the next enzyme evolved.

Doesn't the dynein motor domain jiggle from brownian motion in 3D, such that it would jiggle crosswise or transverse to the microtubule, not just fore and aft along the stalk? Wouldn't that open the probability of transverse movement? I didn't see that indicated in your motion video. Brownian motion doesn't seem to account for progressive movement tho even with the lever arm, just by all its very nature...more like some elecmag attraction being activated between motor domain and microtubule. Just sayin.

[@arkansasmountainman]

When they unload the cargo, how does it get back to the opposite polarity end to get it's next load? They only go one way either + to - or - to + you don't explain that. I see..."Not fully understood" really means "We have no idea"! Which " evolved first" the motors or the ability to create and dismantle the tubular highway? I wonder how the tubular knows when/where it's needed and where to connect to and when to dismantle. It seems to be controlled by some mechanism inside the cell. Would that controller have evolved before or after the tubulars. Hopefully before because the cell would not work. But without the tubulars the cell would not work, and the controller would not be needed. All of those must have all developed or evolved at the same time. How how did they know that was necessary... Seems more like the cell entire cell and it's enormous number of machines would have to evolve fully functional and containing everything instantly. Ain't evolution miraculous? If any one tiny component wasn't there from the very start, the cell would die and dead cells are not going to make anything or evolve. You explain how it moves, now explain how it knows what to move, when to move it and where to move it. How were the loads moved before they evolved? No movement, the cell dies. Dead cells don't evolve.

When scientists investigate the natural world, they don't go about shouting "proof of self-assembly!" They simply follow the evidence. Evolution is sufficient to explain how these things developed.

It's amazing to see that each machine has an inherantly designed task, and so many pefectly exicuted consecutive steps are required for the construction of the DNA into the many components of a fully formed healthy organism. If an amino acid connects to another acid, that is "chance" due to the approximation of the two chems, yet fully functional "working machines" are in no way associated to the word "chance." Each element in the highly complex structure has a proper address, and each machine can access the proper address without any additional motivational stimulant than that for which it was specifically designed. Without the direct intervention of an intelligent biologist, the existence of any working machine, let alone self built over any length of time, is a joke from any mouth. To say that all these atoms could have ever been constructed into any "working complex structure" "which interacts with any other working structure" "to the fulfillment of the DNA's grand plant without each part containing knowledge of the full plan" "all working directly against entropy" again, without intervention or guidance, is absolutly absurd in the upmost degree to any stretch of the imagination(even for an evolutionist's non-scientific opinion).

I am comfortable, however, to say that environmental factors play a key role in the selection of mutations. Motor proteins are proteins coded from RNA from DNA and created by organelles, these mutations, while random, can in rare cases produce a more efficient means of locomotion relative to earlier generations of proteins, more efficient means less cellular energy is lost, more energy can be used for other cellular tasks and ultimately the animal is more fit for survival because of this protein being more efficient. Higher fitness to survive means that it has a higher chance to breed successfully and pass the same type of mutation to it's offspring where they too will be slightly more fit to reproduce.

Thereby nullifying previous "beliefs", which they are. They're not facts, because they're not provable. Thank you, again.

Your explanations are OK. What is nonsensical is your attribution of them to blind chance.
