Well you can tell by my bind to tubulin

Anyone have the variant with the pimp hat and cane twirling?

WHY would they not sync the step with the beat 😩
Psythik@lemmy.world 2 weeks ago
Because they probably don’t understand even basic music theory. Unfortunately far too many people don’t.

Imagine if that protein suddenly gained conciousness and decides to meditate to gain higher spiritual awakening instead of transporting hormones.
kadup@lemmy.world 3 weeks ago
Then a little friendly chaperone protein would come and beat the living shit out of it until it folded itself again and stopped medidating, back to work :)

Better than being ubiquitinized, I guess.

Do they move this slowly? Or is this animation in bullet time?
Valmond@lemmy.world 3 weeks ago
IIRC it’s like 10.000 times faster (I can be wrong but then it’s probably way faster).

I guess this depends on environmental conditions such as
- temperature
- acidity of the internal cell environment
- how available is energy? My guess this mechanism is powered by ATP?

This animation isn’t just sped up, it’s also simplified. In reality they don’t take steady, purposeful steps. They spaz out with random vibrations (Brownian motion) until the “foot” clicks into place by random chance, then the other one releases and the process repeats. It’s like shaking a container filled with legos until they assemble themselves. The proteins are just shaped in such a way that “walking” is the most probable outcome.
exasperation@lemmy.dbzer0.com 2 weeks ago
The animation is actually slowed down. Kinesin can take something like 100 steps per second. Each step is about 8 nm, and they’ve been observed to move 600-1000 nm per second.
In reality it wiggles around in Brownian motion but the equilibrium of it “clicking” into place is so attractive that it keeps happening really fast.

This simulation is famously misleading. Here’s a more accurate representation:

ameancow@lemmy.world 3 weeks ago
Most motor proteins use brownian motion (the random vibration of particles) to “move” and make other actions, but you rarely see any rendering showing what it looks like in real-time because it’s too fast and wiggly. All of these mechanical “clockwork” animations are super-slowed and clarified for better understanding.
There are hundreds of variations of this animation out there which are very similar, some made by major science organizations, so while you’re right that it’s not “true to life” it’s the standard, acceptable model, and not entirely a product of a church. Although I’ve seen plenty of creation-science groups use all kinds of biomechanical motor motion to justify creationism, so it’s hardly matters. They will believe what they want and interpret what they want no mater what.
SaveTheTuaHawk@lemmy.ca 2 weeks ago
I teach cell biology. This is not an acceptable model. Kinesins don’t lift their feet to walk. This is a Disney version of the mechanism.

Jordan117@lemmy.world 3 weeks ago
How is it more accurate? I thought that in reality the “steps” are incredibly fast, but that makes it seem like it’s a much slower and more uncertain process.
yeahiknow3@lemmings.world 3 weeks ago
Fast relative to what? The point is that the kinesin protein doesn’t “walk” any more than floating debris “swims.”
deaf_fish@midwest.social 2 weeks ago
Whoa, does that mean they cool the cell as they walk? They are transferring energy from the Brownian motion which on average would result in a lower temperature in the surrounding particles.
