Summary: Predicted to enable several functions, including Arp2/3 complex binding activity; actin filament binding activity; and profilin binding activity. Involved in intracellular protein transport and regulation of autophagy of mitochondrion. 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 1-cell stage conceptus; central nervous system; genitourinary system; gut; and sensory organ. Orthologous to human CTTN (cortactin).

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
