Ca2+ signaling in HEK-293 and skeletal muscle cells expressing recombinant ryanodine receptors harboring malignant hyperthermia and central core disease mutations.

Abstract excerpt

Malignant hyperthermia (MH) and central core disease (CCD) are caused by mutations in the RYR1 gene encoding the skeletal muscle isoform of the ryanodine receptor (RyR1), a homotetrameric Ca(2+) release channel. Rabbit RyR1 mutant cDNAs carrying mutations corresponding to those in human RyR1 that cause MH and CCD were expressed in HEK-293 cells, which do not have endogenous RyR, and in primary cultures of rat...
