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 By similarity.
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 By similarity.
Subcellular location	Nucleus By similarity. Nucleus membrane; Single-pass membrane protein By similarity. Cytoplasm By similarity. Cell membrane; Single-pass membrane protein By similarity. 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 By similarity.
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 By similarity.
Sequence similarities	Belongs to the chloride channel CLIC family. Contains 1 GST C-terminal domain.
