Volume-regulated anion channel subunit LRRC8E

Gene

Lrrc8e

Organism
Rattus norvegicus (Rat)
Status
Reviewed-Annotation score: -Experimental evidence at transcript leveli

Functioni

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. The VRAC channel conducts iodide better than chloride and may also conduct organic osmolytes like taurine. 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

Interactioni

Subunit structurei

Heterooligomer; heterooligomerizes with other LRRC8 proteins (LRRC8A, LRRC8C, LRRC8D and/or LRRC8B), possibly to form a heterohexamer. In vivo, the subunit composition may depend primarily on expression levels, and heterooligomeric channels containing various proportions of the different LRRC8 proteins may coexist.By similarity
