Cttn Gene Summary [Mouse]

Predicted to enable several functions, including Arp2/3 complex binding activity; profilin binding activity; and proline-rich region binding activity. Involved in intracellular protein transport and regulation of mitophagy. Acts upstream of or within dendritic spine maintenance; negative regulation of extrinsic apoptotic signaling pathway; and substrate-dependent cell migration, cell extension. Located in several cellular components, including cytoskeleton; lamellipodium; and ruffle. Part of voltage-gated potassium channel complex. Is expressed in several structures, including central nervous system; genitourinary system; gut; hemolymphoid system; and sensory organ. Orthologous to human CTTN (cortactin).
