The metabolism of the Xenopus laevis egg provides a cell survival signal. We found previously that increased carbon flux from glucose-6-phosphate (G6P) through pentose phosphate pathway in extracts maintains NADPH levels and calcium/calmodulin regulated protein kinase II (CaMKII) activity to phosphorylate caspase 2 suppress death pathways. Here we show addition G6P oocyte inhibits dephosphorylation/inactivation CaMKII bound by phosphatase 1. Thus, sustains phosphorylation at Ser-135,...
The metabolic status of a cell is fundamentally important factor in deciding whether or not engages its apoptotic machinery. We have previously shown that active metabolism regulates oocyte death via calcium/calmodulin-dependent protein kinase II (CaMKII) mediated phosphorylation caspase-2(1) but the link between activity and CaMKII poorly understood. In this study(2) we identify coenzyme A (CoA) as key signal inhibits Xenopus laevis apoptosis, novel mechanism activation. found CoA directly...
