Crystal Structure Analysis of M32A mutant of human CLIC1Crystal Structure Analysis of M32A mutant of human CLIC1

Structural highlights

3o3t is a 1 chain structure with sequence from Homo sapiens. This structure supersedes the now removed PDB entry 3ma4. Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance.
Method:X-ray diffraction, Resolution 1.7Å
Resources:FirstGlance, OCA, PDBe, RCSB, PDBsum, ProSAT

Function

CLIC1_HUMAN Can insert into membranes and form chloride ion channels. Channel activity depends on the pH. Membrane insertion seems to be redox-regulated and may occur only under oxydizing conditions. Involved in regulation of the cell cycle.[1] [2] [3] [4] [5] [6] [7]

Evolutionary Conservation

Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf.
