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. |
