Summary: Enables identical protein binding activity. Involved in several processes, including cell-matrix adhesion; neurotransmitter receptor transport postsynaptic membrane to endosome; and regulation of cell shape. Located in several cellular components, including cell cortex; nucleoplasm; and ruffle. Is active in GABA-ergic synapse; postsynaptic endosome membrane; and postsynaptic specialization membrane of symmetric synapse. Is expressed in several structures, including alimentary system; heart; limb; nervous system; and sensory organ epithelium. Orthologous to human MKLN1 (muskelin 1).

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.
