Chloride channels of intracellular organelles

Curr Opin Cell Biol. 1995 Aug;7(4):504-8. doi: 10.1016/0955-0674(95)80006-9.

Abstract

Chloride channels are present in a variety of intracellular organelles (Golgi, endosomes, endoplasmic reticulum, and sarcoplasmic reticulum) where they serve largely to shunt the membrane potential created by other ion-translocating processes. Electrophysiological studies have shown that the Cl- channels of the endoplasmic and sarcoplasmic reticula facilitate the efflux of Ca2+. In the Golgi and some endosomes, the open Cl- channels (probably the cystic fibrosis transmembrane conductance regulator) favor accumulation of H+.
