Slc8a2 Gene Summary [Rat]
Enables calcium:monoatomic cation antiporter activity involved in regulation of postsynaptic cytosolic calcium ion concentration and calcium:sodium antiporter activity. Involved in monoatomic cation transmembrane transport; response to vitamin D; and telencephalon development. Acts upstream of or within intracellular calcium ion homeostasis. Located in several cellular components, including dendritic spine; microtubule; and neuronal cell body. Is active in postsynaptic membrane. Biomarker of brain ischemia and status epilepticus. Orthologous to human SLC8A2 (solute carrier family 8 member A2). [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 Slc8a2 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
