>cd03061 GST_N_CLIC GST_N family, Chloride Intracellular Channel (CLIC) subfamily; composed of CLIC1-5, p64, parchorin and similar proteins. They are auto-inserting, self-assembling intracellular anion channels involved in a wide variety of functions including regulated secretion, cell division and apoptosis. They can exist in both water-soluble and membrane-bound states, and are found in various vesicles and membranes. Biochemical studies of the C. elegans homolog, EXC-4, show that the membrane localization domain is present in the N-terminal part of the protein. The structure of soluble human CLIC1 reveals that it is monomeric and it adopts a fold similar to GSTs, containing an N-terminal domain with a TRX fold and a C-terminal alpha helical domain. Upon oxidation, the N-terminal domain of CLIC1 undergoes a structural change to form a non-covalent dimer stabilized by the formation of an intramolecular disulfide bond between two cysteines that are far apart in the reduced form. The CLI
