Protein attributes

Sequence length	253 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is further processed into a mature form.
Protein existence	Evidence at protein level.

General annotation (Comments)

Function	Can insert into membranes and form poorly selective ion channels that may also transport chloride ions. Channel activity depends on the pH. Membrane insertion seems to be redox-regulated and may occur only under oxydizing conditions. Promotes cell-surface expression of HRH3 By similarity. May play a role in angiogenesis.
Subunit structure	Monomer. Interacts with HRH3 By similarity.
Subcellular location	Cytoplasm By similarity. Cytoplasmic vesicle membrane; Single-pass membrane protein By similarity. Nucleus By similarity. Cell membrane; Single-pass membrane protein By similarity. Mitochondrion. Note: Exists both as soluble cytoplasmic protein and as membrane protein with probably a single transmembrane domain. Present in an intracellular vesicular compartment that likely represent trans-Golgi network vesicles By similarity.
Tissue specificity	Detected in blood vessels in the retina (at protein level). Expressed to the greatest extent in vivo in heart, lung, liver, kidney, and skin. Ref.1 Ref.4 Ref.5
Induction	Up-regulated by calcium ions in differentiating keratinocytes. Ref.4
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.
