Ap2s1 Gene Summary [Rat]
Predicted to enable clathrin adaptor activity. Involved in postsynaptic neurotransmitter receptor internalization. Part of AP-2 adaptor complex. Is active in glutamatergic synapse and synaptic vesicle. Is extrinsic component of presynaptic endocytic zone membrane. Human ortholog(s) of this gene implicated in familial hypocalciuric hypercalcemia 3. Orthologous to human AP2S1 (adaptor related protein complex 2 subunit sigma 1).

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 Ap2s1 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
