Scar, a WASp-related protein, activates nucleation of actin filaments by the Arp2y3 complex (polymerizationycell motility)


The Arp2y3 complex, a stable assembly of two actin-related proteins (Arp2 and Arp3) with five other subunits, caps the pointed end of actin filaments and nucleates actin polymerization with low efficiency. WASp and Scar are two similar proteins that bind the p21 subunit of the Arp2y3 complex, but their effect on the nucleation activity of the complex was… (More)
