Crystal Structure of Human Chloride Intracellular Channel protein 2Crystal Structure of Human Chloride Intracellular Channel protein 2

Structural highlights

2per is a 1 chain structure with sequence from Homo sapiens. Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance.
Method:X-ray diffraction, Resolution 2Å
Ligands:
Resources:FirstGlance, OCA, PDBe, RCSB, PDBsum, ProSAT

Disease

CLIC2_HUMAN Note=Defects in CLIC2 are a cause of a mental retardation with cardiopathy and seizures. Cardiac features include atrial fibrillation, cardiomegaly, and congestive heart failure.

Function

CLIC2_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. Modulates the activity of RYR2 and inhibits calcium influx.[1] [2] [3]

Evolutionary Conservation

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