Atp2b2 Gene Summary [Rat]
Enables several functions, including ATP binding activity; P-type calcium transporter activity; and PDZ domain binding activity. Involved in neural retina development. Located in apical plasma membrane; dendritic spine membrane; and neuronal cell body membrane. Is active in several cellular components, including GABA-ergic synapse; parallel fiber to Purkinje cell synapse; and synaptic membrane. Biomarker of brain infarction. Human ortholog(s) of this gene implicated in autosomal dominant nonsyndromic deafness 82 and autosomal recessive nonsyndromic deafness 12. Orthologous to human ATP2B2 (ATPase plasma membrane Ca2+ transporting 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 rat Atp2b2 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
