Function

May act in regulation of cell growth and transformation by interacting with nonreceptor tyrosine kinases ABL1 and/or ABL2. Part of the WAVE complex that regulates lamellipodia formation. The WAVE complex regulates actin filament reorganization via its interaction with the Arp2/3 complex. Regulates ABL1/c-Abl-mediated phosphorylation of MENA. {ECO:0000269PubMed:10498863, ECO:0000269PubMed:7590236, ECO:0000269PubMed:8649853}.

Subcellular Localization

Cytoplasm {ECO:0000250}.Isoform 1: Cell projection, lamellipodium {ECO:0000250}. Cell projection, filopodium {ECO:0000250}. Cytoplasm, cytoskeleton {ECO:0000250}. Note=Isoform 1 but not isoform 3 is localized to protruding lamellipodia and filopodia tips. {ECO:0000250}.
