SeqProS possible 207-270 This region is called GBD(GTPase binding domain). WASP (IID00269) also has GBD, whose sequence is identical to this region and disordered in the free state.
Hetero trimer : IID90008Complex
SeqProS possible 433-453 This region is called WH2 domain. WASP (IID00269) also has WH2, whose sequence is identical to this region and disordered in the free state.
Hetero trimer : IID00265Complex
Regulates actin polymerization by stimulating the actin-nucleating activity of the Arp2/3 complex. Involved in mitosis and cytokinesis, via its role in the regulation of actin polymerization. Binds to HSF1/HSTF1 and forms a complex on heat shock promoter elements (HSE) that negatively regulates HSP90 expression. Plays a role in dendrite spine morphogenesis.
