Rac1 stimulates actin polymerization by activation of WAS protein family (WASF1 and WASF2)

Rac1 binds to NCKAP1 and CYFIP2 and also promotes NCK1 binding to NCKAP1.
This binding inhibits NCKAP1 and CYFIP2 binding to WASF1 and promotes release of the complex of WASF1 and BRK1, thus activating WASF1.
Activated WASF1 then stimulates ARP2/3 that mediates actin cytoskeletal polymerizatioin

Rac1 binds to BAIAP2 which in turn associates with WASF2.
This stimulates ARP2/3 and leads to actin cytoskeleal polymerization.
WAVE2 (so-called WASF2) activates the ARP2/3 complex for Rac-induced actin polymerization during lamellipodium formation
WASF (WAVE) as regulator of actin reorganization downstream of Rac.
Expressed WAVE induces the formation of actin filament clusters.
WAVE plays a critical role downstream of Rac in regulating the actin cytoskeleton required for mem- brane ruffling

WAVE2 serves a functional partner of IRSp53 by regulating its interaction with Rac.

CDC42 induces actin cytoskeleton changes by activating WASP and N-WASP.
WASP and N-WASP binds to ARP2/3 and this lieads to actin cytoskeletal polymerization and filopodia formation.

PAK1 phosphorylates and activates ARP2_3 complex.
