Volume-regulated anion channel subunit LRRC8C

UniProtKB accession:  Q8R502

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Non-essential component of the volume-regulated anion channel (VRAC, also named VSOAC channel), an anion channel required to maintain a constant cell volume in response to extracellular or intracellular osmotic changes (PubMed:29769723). The VRAC channel conducts iodide better than chloride and can also conduct organic osmolytes like taurine (By similarity). Plays a redundant role in the efflux of amino acids, such as aspartate and glutamate, in response to osmotic stress (By similarity). The VRAC channel also mediates transport of immunoreactive cyclic dinucleotide GMP-AMP (2'-3'-cGAMP), an immune messenger produced in response to DNA virus in the cytosol (By similarity). Channel activity requires LRRC8A plus at least one other family member (LRRC8B, LRRC8C, LRRC8D or LRRC8E); channel characteristics depend on the precise subunit composition (By similarity). May play a role in adipogenesis (PubMed:15184384, PubMed:15564382, PubMed:21804215).
