Apba1 Gene Summary [Mouse]

Predicted to enable several functions, including PDZ domain binding activity; amyloid-beta binding activity; and phosphatidylinositol-4,5-bisphosphate binding activity. Involved in presynaptic modulation of chemical synaptic transmission. Acts upstream of or within several processes, including carboxylic acid transport; in utero embryonic development; and locomotory behavior. Located in membrane. Is active in Schaffer collateral - CA1 synapse; glutamatergic synapse; and presynaptic active zone membrane. Is expressed in central nervous system and dorsal root ganglion. Orthologous to human APBA1 (amyloid beta precursor protein binding family A member 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 mouse Apba1 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
