Clcn2 Gene Summary [Rat]
Enables voltage-gated chloride channel activity and volume-sensitive chloride channel activity. Involved in several processes, including cellular hypotonic response; positive regulation of oligodendrocyte differentiation; and positive regulation of voltage-gated chloride channel activity. Located in several cellular components, including axon initial segment; dendritic spine membrane; and perikaryon. Used to study cystic fibrosis. Human ortholog(s) of this gene implicated in primary hyperaldosteronism. Orthologous to human CLCN2 (chloride voltage-gated channel 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 Clcn2 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
