Ap2a1 Gene Summary [Rat]
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, Jul 2025]

Protein Domains
A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in rat Ap2a1 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
