Slc8a1 Gene Summary [Mouse]
Enables ankyrin binding activity; calcium:sodium antiporter activity; and transmembrane transporter binding activity. Involved in several processes, including cellular response to caffeine; metal ion transport; and vascular associated smooth muscle contraction. Acts upstream of or within several processes, including embryonic organ development; metal ion transport; and regulation of macromolecule metabolic process. Located in several cellular components, including T-tubule; basolateral plasma membrane; and postsynaptic density. Is expressed in several structures, including alimentary system; central nervous system; genitourinary system; heart; and nose. Human ortholog(s) of this gene implicated in hypertension. Orthologous to human SLC8A1 (solute carrier family 8 member A1). [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 Slc8a1 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
