GeneCards Summary for ITPR1 Gene

ITPR1 (Inositol 1,4,5-Trisphosphate Receptor Type 1) is a Protein Coding gene. Diseases associated with ITPR1 include Spinocerebellar Ataxia 15 and Spinocerebellar Ataxia 29. Among its related pathways are DAG and IP3 signaling and Neuroscience. Gene Ontology (GO) annotations related to this gene include ion channel activity and calcium channel activity. An important paralog of this gene is ITPR2.

UniProtKB/Swiss-Prot Summary for ITPR1 Gene

  • Intracellular channel that mediates calcium release from the endoplasmic reticulum following stimulation by inositol 1,4,5-trisphosphate (PubMed:27108797). 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).

Tocris Summary for ITPR1 Gene

  • Inositol 1,4,5-trisphosphate (IP3) receptors are a form of ligand-gated ion channels that are activated by cytosolic Ca2+ and IP3. They are localized to intracellular membranes, such as the endoplasmic reticulum, and mediate the mobilization of intracellular Ca2+ stores.

    Size:
    2758 amino acids
    Molecular mass:
    313929 Da
    Quaternary 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 IRAG1 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 (PubMed:16793548). Interacts with AHCYL2 (with lower affinity than with AHCYL1) (PubMed:19220705). Interacts with BOK (via BH4 domain); protects ITPR1 from proteolysis by CASP3 during apoptosis (PubMed:23884412).
    Miscellaneous:
    • Calcium appears to inhibit ligand binding to the receptor, most probably by interacting with a distinct calcium-binding protein which then inhibits the receptor.

Post-translational modifications for ITPR1 Gene

  • 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.
  • Glycosylation at Asn2512
  • Ubiquitination at Lys917, Lys972, Lys1581, Lys1780, Lys1893, Lys1894, Lys1895, Lys1910, Lys1933, Lys2127, and Lys2266

ITPR1_HUMAN
  • Spinocerebellar ataxia 15 (SCA15) [MIM:606658]: Spinocerebellar ataxia is a clinically and genetically heterogeneous group of cerebellar disorders. Patients show progressive incoordination of gait and often poor coordination of hands, speech and eye movements, due to degeneration of the cerebellum with variable involvement of the brainstem and spinal cord. SCA15 is an autosomal dominant cerebellar ataxia (ADCA). It is very slow progressing form with a wide range of onset, ranging from childhood to adult. Most patients remain ambulatory. {ECO:0000269 PubMed:17590087, ECO:0000269 PubMed:18579805}. Note=The disease is caused by mutations affecting the gene represented in this entry.
  • Spinocerebellar ataxia 29 (SCA29) [MIM:117360]: An autosomal dominant, congenital spinocerebellar ataxia characterized by early motor delay, hypotonia and mild cognitive delay. Affected individuals develop a very slowly progressive or non-progressive gait and limb ataxia associated with cerebellar atrophy on brain imaging. Additional variable features include nystagmus, dysarthria, and tremor. {ECO:0000269 PubMed:22986007, ECO:0000269 PubMed:26770814}. Note=The disease is caused by mutations affecting the gene represented in this entry.
  • Gillespie syndrome (GLSP) [MIM:206700]: A rare disease characterized by bilateral iris hypoplasia, congenital hypotonia, non-progressive ataxia, progressive cerebellar atrophy, and mental retardation. {ECO:0000269 PubMed:27108797, ECO:0000269 PubMed:27108798}. Note=The disease is caused by mutations affecting the gene represented in this entry.
