Chloride (Cl-) channels are membrane, anion-selective protein pores, which diffusively transport negative ions across their electrochemical gradient. Cl- channels are subdivided into six unique families, and their regulation mechanisms range from voltage-dependency, through G-protein activation, to mechanosensitivity; they may reside in either the plasma membrane or the membrane of intracellular compartments or both1. They are detected in the kidney, placenta, intestines, brain and the inner-ear1-4.
The vertebrate Cl- intracellular channel (CLIC) family is composed of 6 highly conserved members (CLIC1-6); each exists as a ~250 residue protein which can assume both a soluble fold and a membrane-integral form. The latter consists of a single trans-membrane domain and is subsequently oligomerized to construct a functioning channel1,5. Interestingly, channels composed of CLIC4 and CLIC5 have been confirmed to be equally permeable to K+ and Cl-5.
CLIC5, to which there are two isoforms - CLIC5A and CLIC5B - encoded by the same gene5, has first been isolated from human placenta6, and was shown, together with CLIC4 (with which it shares 76% homology), to be enriched in the apical microvilli-containing part of the trophoblast epithelium, where, unlike CLIC4, it interacts with the actin cytoskeleton4. CLIC5 shares about 40% homology with CLIC1-4 and is distributed to a high degree in myocytes, cardiomyocytes and stereocillia of the inner-ear2,4. Mice mutated in the Clic5 gene lack coordination and gradually become deaf2, show resistance to obesity, experience gastric ulcers and the resultant hemorrhage, and have higher incidence of entering torpor7.
Species reactivity key:
Anti-CLIC5 Antibody (#ACL-025) is a highly specific antibody directed against an epitope of the rat protein. The antibody can be used in western blot, immunocytochemistry and immunohistochemistry applications. It has been designed to recognize CLIC5 from mouse, rat, and human samples.
