Double-stranded-RNA-activated protein kinase (PKR) regulates Ca2+ stores in Xenopus oocytes.

D Thomas1, H Y Kim, R Morgan, M R Hanley.   

Abstract

Expression of the double-stranded-RNA-dependent protein kinase (PKR) in Xenopus oocytes attenuated Ca2+ entry-dependent membrane currents activated by depletion of Ca2+ stores, whereas expression of a dominant-negative PKR mutant had the opposite effect. These results appeared to be due to perturbation of releasable Ca2+ stores, and not actions of PKR on protein synthesis. PKR may thus have novel protein substrates and cellular functions in Ca2+ storage and signalling.
