Research Backgrounds

Function:

Intracellular channel that mediates calcium release from the endoplasmic reticulum following stimulation by inositol 1,4,5-trisphosphate. Involved in the regulation of epithelial secretion of electrolytes and fluid through the interaction with AHCYL1 (By similarity). 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 (By similarity).

PTMs:

Phosphorylated on tyrosine residues.

Ubiquitination at multiple lysines targets ITPR1 for proteasomal degradation. Approximately 40% of the ITPR1-associated ubiquitin is monoubiquitin, and polyubiquitins are both 'Lys-48'- and 'Lys-63'-linked (By similarity).

Phosphorylated by cAMP kinase (PKA). Phosphorylation prevents the ligand-induced opening of the calcium channels. Phosphorylation by PKA increases the interaction with inositol 1,4,5-trisphosphate and decreases the interaction with AHCYL1.

Palmitoylated by ZDHHC6 in immune cells, leading to regulate ITPR1 stability and function.

Tissue Specificity:

Widely expressed.

Subunit Structure:

Homotetramer. Interacts with TRPC4. The PPXXF motif binds HOM1, HOM2 and HOM3. Interacts with RYR1, RYR2, ITPR1, SHANK1 and SHANK3. Interacts with ERP44 in a pH-, redox state- and calcium-dependent manner which results in the inhibition the calcium channel activity. The strength of this interaction inversely correlates with calcium concentration. Part of cGMP kinase signaling complex at least composed of ACTA2/alpha-actin, CNN1/calponin H1, PLN/phospholamban, PRKG1 and ITPR1. Interacts with MRVI1 and CABP1 (via N-terminus). Interacts with TESPA1. Interacts (when not phosphorylated) with AHCYL1 (when phosphorylated); the interaction suppresses inositol 1,4,5-trisphosphate binding to ITPR1. Interacts with AHCYL2 (with lower affinity than with AHCYL1). Interacts with BOK (via BH4 domain); protects ITPR1 from proteolysis by CASP3 during apoptosis.

Family&Domains:

The receptor contains a calcium channel in its C-terminal extremity. Its large N-terminal cytoplasmic region has the ligand-binding site in the N-terminus and modulatory sites in the middle portion immediately upstream of the channel region.

Belongs to the InsP3 receptor family.
