Summary: Enables Arp2/3 complex binding activity and proline-rich region binding activity. Involved in several processes, including focal adhesion assembly; modification of postsynaptic actin cytoskeleton; and plasma membrane bounded cell projection organization. Located in several cellular components, including actin filament; clathrin-coated pit; and focal adhesion. Part of voltage-gated potassium channel complex. Is active in glutamatergic synapse and postsynaptic actin cytoskeleton. Orthologous to human CTTN (cortactin). [provided by Alliance of Genome Resources, Dec 2024]

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.
