Look at that swagger!
I think I’d swagger too if my scrotum dragged along behind me like that!
I don’t know if it’s the funniest ever, but I’d put it in the top 5.
Looks more R. Crumbesque to me.
Keep on truckin, little protein.
From the Ministry of Silly Protein Walks.
Is it weird that I recognize the source video from a college biology course? It was a pretty great PBS special, I think.
Yeah, it’s from the Inner Life of the Cell:
It’s a few minutes long, and a visualization of molecular biology made by some folks at Harvard. It’s also nerdy awesomeness.
*sigh*…Yes, nerdily awesome.
It’s good that CG is utilized in this manner these days, but I sure wish the animation revolution had occurred before I was in school. I’m one of those people who had to SEE how it worked, and not just take some beeping filmstrip at its word.
What is this? I don’t even…
Just pretend you’re climbing up a rope while holding onto another rope, which is attached to a lever. That’s how a muscle would tighten to bend an arm.
“Well you can tell by the way I use my walk….”
What is that? Actin?
That is the motor protein Kinesin “walking” along a microtubule carrying a storage vesicle(sack). Microtubules are a part of the cells internal skeleton like actin but they form larger, hollow fibers out of the protein tubulin and they serve different roles.
That is probably dynein/dynactin walking along a microtubule. Or kinesin? I worked on tubulin (Drosphila beta3 in the hizzouse!) but I never could remember my motor proteins. Need to know about EMEF motif where they stick their little feets, though, and I’m your gal.
They see me rollin’
They trying to catch me walkin’ dirty (which I AAAAAAM)
you know when a nerdy magazine uses the urban phrase “haters gonna hate”, it’s time to retire the phrase…
I was using “haters gonna hate” before it was cool. Now I use “boop beep boop – droids”. You’ve probably never heard of it. I’ve only just put the sticker on my fixie.
Have an artisinal bacon cupcake, “spejic”
And for those of us whose first language is English?
I knew microtubules were kind of like spokes in a spherical wheel, but I didn’t know they were tiny walkways for these groovy little jiggers!
Awesome. Biology: fucking guaranteed to blow your mind.
The visualization was commissioned by Harvard. It was done by the folks at XVIVO, http://www.xvivo.net/.
I buy that this is all accepted or well worked out science, but many many times in that video it seems like the voice over guy is just making shit up.
