Stromal interaction molecule 1

UniProtKB accession:  G5EF60

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Plays a role in mediating store-operated Ca(2+) entry (SOCE), a Ca(2+) influx following depletion of intracellular Ca(2+) stores. Acts as a Ca(2+) sensor which upon Ca(2+) depletion, activates the Ca(2+) release-activated Ca(2+) (CRAC) channel subunit, orai-1. Essential for Ca (2+) and IP3-dependent contractile activity of gonad sheath cells and spermatheca. Essential for fertility. Does not play a role in posterior body wall muscle contraction (pBoc) rhythmicity, intestinal cell oscillatory Ca(2+) signaling or intestinal ER Ca(2+) hemostasis.
