Abstract
An application of a RyR2 protein or a recombinant RyR2 protein in preparing an anti-heart failure medicament is provided. The recombinant RyR2 protein is a naturally occurring RyR2 protein fragment or a mutant, such as a SPRY1 domain protein, a P1 domain protein, a SPRY2 domain protein, a SPRY3 domain protein, a Handle domain protein, an HD1 domain protein, an HD2 domain protein, a central domain protein, an EF-hand domain protein, a U-motif protein, a P2 domain protein, a P2 domain fragment protein-1, a P2 domain fragment protein-2 derived from a natural RyR2 protein or a P2 mutant derived from the natural RyR2 protein. The exogenous recombinant RyR2 protein is highly expressed in both normal small animal and diseased small animal models, so that the left ventricular ejection fraction of experimental animals is improved varying degrees compared with that of a control group.
