功能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.
序列相似性Belongs to the ABI family. Contains 1 SH3 domain. Contains 1 t-SNARE coiled-coil homology domain.
翻译后修饰Is a substrate for ABL1.
细胞定位Cytoplasm and Cell projection > lamellipodium. Cell projection > filopodium. Cytoplasm > cytoskeleton. Isoform 1 but not isoform 3 is localized to protruding lamellipodia and filopodia tips.
