Apba2 Gene Summary [Mouse]
Predicted to enable amyloid-beta binding activity and identical protein binding activity. Involved in presynaptic modulation of chemical synaptic transmission. Acts upstream of or within several processes, including chemical synaptic transmission; in utero embryonic development; and locomotory behavior. Is active in Schaffer collateral - CA1 synapse. Is expressed in several structures, including alimentary system; nervous system; respiratory system; sensory organ; and skeleton. Orthologous to human APBA2 (amyloid beta precursor protein binding family A member 2). [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 Apba2 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
