| Research Abstract |
In the heart, calcium plays important roles in excitation-contraction (E-C) coupling. SERCA2a and ryanodine receptor (RyR2) are two major Ca^<2+> signaling proteins involving in E-C coupling. The activity of these proteins is regulated by their accessory proteins, which may play an important role in the pathogenesis of heart failure. Sorcin is the one of the protein that is associated with RyR2
The expression level of sorcin was altered in remodeling hearts. In order to elucidate a role of sorcin in the heart, we generated sorcin knockout mice. The mice showed no abnormal E-C coupling.
