LRRC8A
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. The VRAC channel conducts iodide better than chloride and can also conduct organic osmolytes like taurine. Mediates efflux of amino acids, such as aspartate and glutamate, in response to osmotic stress. LRRC8A and LRRC8D are required for the uptake of the drug cisplatin. Required for in vivo channel activity, together with at least one other family member (LRRC8B, LRRC8C, LRRC8D or LRRC8E); channel characteristics depend on the precise subunit composition. Can form functional channels by itself (in vitro). Involved in B-cell development: required for the pro-B cell to pre-B cell transition. Also required for T-cell development. Belongs to the LRRC8 family. Expressed in brain, kidney, ovary, lung, liver, heart, and fetal brain and liver. Found at high levels in bone marrow; lower levels are detected in peripheral blood cells. Expressed on T-cells as well as on B-lineage cells.
