domain:Binds the Arp2/3 complex through the C-terminal region and actin through verprolin homology (VPH) domain. ,function:Downstream effector molecules involved in the transmission of signals from tyrosine kinase receptors and small GTPases to the actin cytoskeleton. ,similarity:Belongs to the SCAR/WAVE family. ,similarity:Contains 1 WH2 domain. ,subcellular location:Dot-like pattern in the cytoplasm. Concentrated in Rac-regulated membrane-ruffling areas. ,subunit:Component of the WAVE1 complex composed of ABI2 , CYFIP2 , C3orf10/HSPC300 , NCKAP1 and WASF1/WAVE1. CYFIP2 binds to activated RAC1 which causes the complex to dissociate , releasing activated WASF1. The complex can also be activated by NCK1 (By similarity) . Binds actin and the Arp2/3 complex. Interacts with BAIAP2. ,tissue specificity:Highly expressed in brain. Lowly expressed in testis , ovary , colon , kidney , pancreas , thymus , small intestine and peripheral blood. ,
