High impact information on Casq1

 

Chemical compound and disease context of Casq1

  • Transgenic mice with cardiac-targeted calsequestrin overexpression show marked suppression of Ca(2+)-induced Ca(2+) release, myocyte hypertrophy, and premature death by 16 weeks of age (Jones, L. R., Suzuki, Y. J., Wang, W., Kobayashi, Y. M., Ramesh, V., Franzini-Armstrong, C., Cleemann, L., and Morad, M. (1998) J. Clin. Invest. 101, 1385-1393) [8].

Associations of Casq1 with chemical compounds

  • The mRNA levels of angiotensin II type1a receptor which requires AP-1 and GATA-4 for gene transcription was suppressed in CSQ overexpressing hearts [10].
  • Calsequestrin (CSQ) is a high capacity Ca(2+)-binding protein present in the lumen of sarcoplasmic reticulum (SR) in striated muscle cells and has been shown to regulate the ryanodine receptor Ca(2+) release channel activity through interaction with other proteins present in the SR [14].
  • These results indicate that the aspartate-rich segment of CSQ, under conditions of overexpression, can sustain structural interactions that interfere with the SOCE mechanism [14].
  • CS (calsequestrin) is an acidic glycoprotein of the SR (sarcoplasmic reticulum) lumen and plays a crucial role in the storage of Ca2+ and in excitation-contraction coupling of skeletal muscles [13].
  • This apparent lower responsiveness of ICa to cAMP could be reversed by the non-hydrolysable cAMP analogue 8-Br-cAMP or the phosphodiesterase inhibitor IBMX, suggesting high phosphodiesterase activity of CSQ myocytes [3].
