Novel sarco(endo) plasmic reticulum proteins and calcium homeostasis in striated muscles

The impact of calcium signaling on many cellular functions is reflected by the tight regulation of the intracellular Ca2+ concentration that is ensured by diverse pumps, channels, transporters and Ca2+ binding proteins. In this review, we present recently identified novel sarco(endo) plasmic reticulum proteins that may have a potential involvement in the regulation of Ca2+ homeostasis in striated muscles.
