General annotation (Comments)

Function

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. Ref.1 Ref.12 Ref.13 Ref.15 Ref.16 Ref.22 Ref.23

Subunit structure

Monomer. Homodimer (in vitro). Interacts with TRAPPC2. Dimerization requires a conformation change that leads to the exposure of a large hydrophobic surface. In vivo, this may lead to membrane insertion. Interacts with AKAP9. Ref.17 Ref.18 Ref.23

Subcellular location

Nucleus. Nucleus membrane; Single-pass membrane protein Probable. Cytoplasm. Cell membrane; Single-pass membrane protein Probable. Note: Mostly in the nucleus including in the nuclear membrane. Small amount in the cytoplasm and the plasma membrane. Exists both as soluble cytoplasmic protein and as membrane protein with probably a single transmembrane domain. Ref.1 Ref.14 Ref.15 Ref.18 Ref.22

Tissue specificity

Expression is prominent in heart, placenta, liver, kidney and pancreas. Ref.14

Domain

Members of this family may change from a globular, soluble state to a state where the N-terminal domain is inserted into the membrane and functions as chloride channel. A conformation change of the N-terminal domain is thought to expose hydrophobic surfaces that trigger membrane insertion. Ref.19 Ref.22 Ref.23

Post-translational modification

Hydrogen peroxide treatment causes a conformation change, leading to dimerization and formation of an intramolecular disulfide bond between Cys-24 and Cys-59.

Miscellaneous

The protein seems to have very low affinity for glutathione, even though glutathione binding was observed in protein crystals.

Sequence similarities

Belongs to the chloride channel CLIC family.

Contains 1 GST C-terminal domain.
