Predicted to enable protein domain specific binding activity and protein kinase binding activity. Involved in G protein-coupled receptor signaling pathway and platelet-derived growth factor receptor signaling pathway. Acts upstream of or within cell migration. Located in several cellular components, including actin cytoskeleton; focal adhesion; and lamellipodium. Is expressed in several structures, including alimentary system; brain; eye; genitourinary system; and hemolymphoid system gland. Human ortholog(s) of this gene implicated in breast ductal carcinoma. Orthologous to human BCAR1 (BCAR1 scaffold protein, Cas family member). [provided by Alliance of Genome Resources, Apr 2022]
