Gene Symbol LRRC8B
Protein Name leucine rich repeat containing 8 family, member B
Synonyms TA-LRRP; TALRRP;
Species Homo sapiens
Ensembl Protein ENSP00000332674
InnateDB Gene IDBG-100188 (LRRC8B)
Protein Structure
UniProt Annotation
Function 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. The VRAC channel conducts iodide better than chloride and may also conduct organic osmolytes like taurine. It is unclear whether LRRC8B constitutes a pore-forming subunit or whether it is closely associated with the pore (By similarity). {ECO:0000250}.
Subcellular Localization Cell membrane {ECO:0000250}; Multi-pass membrane protein {ECO:0000250}.
