Ap1s2 Gene Summary [Mouse]
Predicted to enable clathrin adaptor activity. Involved in synaptic vesicle budding from endosome. Acts upstream of or within several processes, including adipose tissue development; fat cell differentiation; and visual learning. Predicted to be located in Golgi apparatus. Predicted to be part of AP-1 adaptor complex. Predicted to be active in intracellular membrane-bounded organelle. Is expressed in mesonephros; neocortex; and urinary system. Used to study syndromic X-linked intellectual disability 5. Human ortholog(s) of this gene implicated in syndromic X-linked intellectual disability 5. Orthologous to human AP1S2 (adaptor related protein complex 1 subunit sigma 2). [provided by Alliance of Genome Resources, Apr 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 mouse Ap1s2 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
