Arp2/3 complex mediated actin nucleation

Updated March 2013: Arp2/3 is a protein complex of seven subunits that is involved in the nucleation and assembly of branched actin filaments. The Arp2/3 complex is highly conserved and is found in most eukaryotes. Branched nucleation by the Arp2/3 complex requires a preformed actin filament and is regulated by proteins such as WASp and Cdc42 which are depicted in this animation using stylized schematic models.

I think the absence of a narration helped make me pay better attention the visually demonstrated molecular process. Good job!

This really helped me understand the research article I'm reading. Thank you.

Thank you so much, this is the best so far.

Excellent video, thank you very much!

Is it not WCA ?
Because W comes from WASP homology-2 domain
C Central region
A acidic region.
