function:Regulates actin polymerization by stimulating the actin-nucleating activity of the Arp2/3 complex. Binds to HSF1/HSTF1 and forms a complex on heat shock promoter elements (HSE) that negatively regulates HSP90 expression.,similarity:Contains 1 CRIB domain.,similarity:Contains 1 WH1 domain.,similarity:Contains 2 WH2 domains.,subcellular location:Preferentially localized in the cytoplasm when phosphorylated and in the nucleus when unphosphorylated.,subunit:Binds actin and the Arp2/3 complex. Interacts with CDC42. Binds to SH3 domains of GRB2. Interacts with the C-terminal SH3 domain of DNMBP. Interacts with the WW domains of PRPF40A/FBP11 (By similarity). Interacts with NOSTRIN. Interacts with Shigella flexneri protein icsA. The interaction with icsA enhances the affinity of WASL for Arp2/3, thus assembling a tight complex which has maximal activity in actin assembly.,
Cytoplasm, cytoskeleton . Nucleus . Cytoplasm . Preferentially localized in the cytoplasm when phosphorylated and in the nucleus when unphosphorylated (By similarity). Exported from the nucleus by an nuclear export signal (NES)-dependent mechanism to the cytoplasm (By similarity). .
