Slc8b1 Gene Summary [Rat]
Enables protein homodimerization activity. Predicted to be involved in several processes, including calcium export from the mitochondrion; intracellular calcium ion homeostasis; and regulation of cardiac muscle cell membrane potential. Predicted to act upstream of or within calcium ion transmembrane transport and sodium ion transmembrane transport. Located in mitochondrial crista and sarcolemma. Orthologous to human SLC8B1 (solute carrier family 8 member B1). [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 Slc8b1 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
