Function

Chloride channels have several functions including the regulation of cell volume; membrane potential stabilization; signal transduction and transepithelial transport (By similarity). Involved in the regulation of aldosterone production. The opening of CLCN2 channels at hyperpolarized membrane potentials in the glomerulosa causes cell membrane depolarization; activation of voltage-gated Ca2+ channels and increased expression of aldosterone synthase; the rate-limiting enzyme for aldosterone biosynthesis (By similarity).
