Post Translational Modifications | Polyubiquitinated. Polyubiquitination targets ITPR1 for proteasomal degradation. Approximately 40% of the ITPR1-associated ubiquitin is monoubiquitin, and polyubiquitins are both 'Lys-48'- and 'Lys-63'-linked. Phosphorylated by cAMP kinase (PKA) enhances calcium release. Phosphorylation by PKA increases the interaction with inositol 1,4,5-trisphosphate and decreases the interaction with AHCYL1. Phosphorylated on tyrosine residues. Palmitoylated by ZDHHC6 in immune cells, leading to regulation of ITPR1 stability and function. |
Function | Inositol 1,4,5-trisphosphate-gated calcium channel that, upon inositol 1,4,5-trisphosphate binding, mediates calcium release from the endoplasmic reticulum (ER). Undergoes conformational changes upon ligand binding, suggesting structural flexibility that allows the channel to switch from a closed state, capable of interacting with its ligands such as 1,4,5-trisphosphate and calcium, to an open state, capable of transferring calcium ions across the ER membrane. Cytoplasmic calcium released from the ER triggers apoptosis by the activation of CAMK2 complex. Involved in the regulation of epithelial secretion of electrolytes and fluid through the interaction with AHCYL1. Part of a complex composed of HSPA9, ITPR1 and VDAC1 that regulates mitochondrial calcium-dependent apoptosis by facilitating calcium transport from the ER lumen to the mitochondria intermembrane space thus providing calcium for the downstream calcium channel MCU that directly releases it into mitochondria matrix. Regulates fertilization and egg activation by tuning the frequency and amplitude of calcium oscillations. |
