    Summary
    Predicted to enable AP-1 adaptor complex binding activity; Arp2/3 complex binding activity; and kinesin binding activity. Acts upstream of or within several processes, including negative regulation of cell motility; negative regulation of substrate adhesion-dependent cell spreading; and regulation of Arp2/3 complex-mediated actin nucleation. Located in endosome. Is expressed in several structures, including cardiovascular system; genitourinary system; gut; integumental system; and nervous system. Orthologous to human AP1AR (adaptor related protein complex 1 associated regulatory protein). [provided by Alliance of Genome Resources, Jul 2025]

    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.
