Motor protein Memes

Sisyphus had it easy compared to kinesin. This tiny protein literally spends its entire existence hauling cellular cargo up a microtubule mountain, one ATP-fueled step at a time. Meanwhile, dynein's just working the downhill shift. Sure, kinesin looks happy in this cleverly edited image of Sisyphus, but that's just the ATP talking. The protein equivalent of your morning coffee, except it needs about a million cups per second. And you thought your commute was rough.
