    Summary
    Predicted to enable clathrin adaptor activity; low-density lipoprotein particle receptor binding activity; and protein kinase binding activity. Involved in positive regulation of neuron projection development and positive regulation of receptor-mediated endocytosis. Located in apical plasma membrane; basolateral plasma membrane; and clathrin-coated vesicle. Part of protein-containing complex. Is active in synaptic vesicle. Orthologous to human AP2A1 (adaptor related protein complex 2 subunit alpha 1). [provided by Alliance of Genome Resources, Nov 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.
