Mouse Anti-EFCAB4B (EF-hand Calcium-binding Domain-containing Protein 4B, Calcium Release-activated Calcium Channel Regulator 2A, CRAC Channel Regulator 2A, CRACR2A, DKFZp686G13246, FLJ33046, FLJ33805, MGC4266)
Ca(2+)-binding protein that plays a key role in store-operated Ca(2+) entry (SOCE) in T-cells by regulating CRAC channel activation. Acts as a cytoplasmic calcium-sensor that facilitates the clustering of ORAI1 and STIM1 at the junctional regions between the plasma membrane and the endoplasmic reticulum upon low Ca(2+) concentration. It thereby regulates CRAC channel activation, including translocation and clustering of ORAI1 and STIM1. Upon increase of cytoplasmic Ca(2+) resulting from opening of CRAC channels, dissociates from ORAI1 and STIM1, thereby destabilizing the ORAI1-STIM1 complex.
