Protein Name: Chloride intracellular channel protein 4

UniprotKB/SwissProt ID: CLIC4_HUMAN (Q9Y696)

Gene Name: CLIC4

Organism: Homo sapiens (Human).

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. Has alternate cellular functions like a potential role in angiogenesis or in maintaining apical- basolateral membrane polarity during mitosis and cytokinesis. Could also promote endothelial cell proliferation and regulate endothelial morphogenesis (tubulogenesis).

Protein Subcellular Localization: Cytoplasm, cytoskeleton, microtubule organizing center, centrosome. Cytoplasmic vesicle membrane; Single-pass membrane protein (Probable). Nucleus matrix. Cell membrane; Single-pass membrane protein (Probable). Mitochondrion. Cell junction. Note=Colocali
