Crystal structure of a soluble form of CLIC1. An intracellular chloride ion channel
OverviewOverview
CLIC1 (NCC27) is a member of the highly conserved class of chloride ion, channels that exists in both soluble and integral membrane forms. Purified, CLIC1 can integrate into synthetic lipid bilayers forming a chloride, channel with similar properties to those observed in vivo. The structure, of the soluble form of CLIC1 has been determined at 1.4-A resolution. The, protein is monomeric and structurally homologous to the glutathione, S-transferase superfamily, and it has a redox-active site resembling, glutaredoxin. The structure of the complex of CLIC1 with glutathione shows, that glutathione occupies the redox-active site, which is adjacent to an, open, elongated slot lined by basic residues. Integration of CLIC1 into, the membrane is likely to require a major structural rearrangement, probably of the N-domain (residues 1-90), with the putative transmembrane, helix arising from residues in the vicinity of the redox-active site. The, structure indicates that CLIC1 is likely to be controlled by, redox-dependent processes.
