Summary: Enables protein kinase binding activity. Involved in clathrin-dependent endocytosis and synaptic vesicle endocytosis. Located in filopodium tip. Part of AP-2 adaptor complex. Is active in glutamatergic synapse and postsynaptic endocytic zone. Is expressed in brain; cranial ganglion; dorsal root ganglion; and liver. 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.
