Slc4a8 Gene Summary [Mouse]
Enables sodium,bicarbonate:chloride antiporter activity. Involved in regulation of synaptic vesicle exocytosis. Acts upstream of or within positive regulation of synaptic vesicle exocytosis and regulation of intracellular pH. Located in several cellular components, including basolateral plasma membrane; neuronal cell body membrane; and presynapse. Is active in glutamatergic synapse and presynaptic membrane. Is expressed in several structures, including adrenal gland; alimentary system; genitourinary system; nervous system; and sensory organ. Orthologous to human SLC4A8 (solute carrier family 4 member 8). [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 Slc4a8 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
