Target Background

Function
Calsequestrin is a high-capacity, moderate affinity, calcium-binding protein and thus acts as an internal calcium store in muscle. Calcium ions are bound by clusters of acidic residues at the protein surface, often at the interface between subunits. Can bind around 80 Ca(2+) ions. Regulates the release of lumenal Ca(2+) via the calcium release channel RYR1; this plays an important role in triggering muscle contraction. Negatively regulates store-operated Ca(2+) entry (SOCE) activity.
Gene References into Functions
  1. These results widen the spectrum of skeletal muscle diseases associated with CASQ1 and indicate that these mutations affect properties critical for correct Ca(2+) handling in skeletal muscle fibers. PMID: 28895244
  2. the p.D244G variant in CASQ1 is associated with a skeletal muscle disease and alters sarcoplasmic calcium release PMID: 27196359
  3. Calsequestrin-1 monomers suppress Store-Operated Ca2+ Entry by interacting with STIM1 and attenuating STIM1 aggregation via its C-terminal amino acid 362-396. PMID: 27185316
  4. the protein aggregate myopathy with benign evolution and muscle inclusions composed of excess CASQ1 due to the D244G heterozygous missense mutation in the CASQ1 gene PMID: 26136523
  5. Equilibrium dialysis and turbidity measurements showed that D244G and, to a lesser extent, M87T partially lose Ca(2+) binding exhibited by wild type calsequestrin 1 at high Ca(2+) concentrations. PMID: 26416891
  6. Missense mutation in CASQ1 gene causes the formation of abnormal sarcoplasmic reticulum (SR) vacuoles containing aggregates of CASQ1 results in altered Ca2+ release, and vacuolar myopathy patients phenotype. PMID: 25116801
  7. There is a significant association between SNP A175G and heat stroke. PMID: 24887214
  8. The sarcoplasmic reticulum calcium content in human type II fibres is primarily determined by the CSQ1 abundance, and in type I fibres, by the combined amounts of both CSQ1 and CSQ2. PMID: 24127619
  9. a direct interaction of dysferlin with Trim72/MG53, AHNAK, cytoplasmic dynein, myomesin-2 and calsequestrin-1, but not with caveolin-3 or dystrophin, is reported. PMID: 23792176
  10. CASQ1 is not a major malignant hyperthermia susceptibility locus in the North American population PMID: 23460944
  11. Downregulation of CSQ-1 in diabetic platelets and impairment of CSQ-1 in normal cells leads to disturbed Ca(2+) release, demonstrating a potential role for CSQ-1 in the regulation of the platelet Ca(2+) release process PMID: 22060633
  12. a mechanism for the observed in vitro and in vivo dynamic high-capacity and low-affinity Ca(2+)-binding activity of calsequestrin PMID: 22337878
  13. Single nucleotide polymorphisms within CASQ1 were genotyped in Amish subjects with type 2 diabetes, glucose intolerance and normals. PMID: 15561962
  14. Noncoding single nucleotide polymorphisms in CASQ1 alter diabetes susceptibility, either by a direct effect on CASQ1 gene expression or perhaps by regulating a nearby gene. PMID: 15561963
  15. CASQ1 polymorphism is not associated with type 2 diabetes PMID: 17681849
