ITPR1_HUMAN

Intracellular channel that mediates calcium release from the endoplasmic reticulum following stimulation by inositol 1,4,5-trisphosphate (PubMed). Involved in the regulation of epithelial secretion of electrolytes and fluid through the interaction with AHCYL1 . Plays a role in ER stress-induced apoptosis. Cytoplasmic calcium released from the ER triggers apoptosis by the activation of CaM kinase II, eventually leading to the activation of downstream apoptosis pathways . [View more on UniProt]
