Volume-regulated anion channel subunit LRRC8B (LRRC8B)

Non-essential part of the volume-regulated anion channel (VRAC, also called VSOAC station ), 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 such as taurine.

Channel activity demands LRRC8A plus at least one other family member (LRRC8B, LRRC8C, LRRC8D or LRRC8E); channel characteristics depend on the exact subunit composition. .
