Members of the Bcl-2 protein family play a central role in the regulation of apoptosis. An interaction between anti-apoptotic Bcl-x(L) and the endoplasmic reticulum (ER)-localized inositol trisphosphate receptor Ca(2+) release channel (InsP(3)R) enables Bcl-x(L) to be fully efficacious as an anti-apoptotic mediator (White, C., Li, C., Yang, J., Petrenko, N.(More)
Bcl-2 proteins are major regulators of cellular responses to intrinsic and extrinsic apoptotic stimuli. Among them, overexpression of the antiapoptotic protein Bcl-x(L) modulates intracellular Ca(2+) homeostasis and organelle-specific apoptotic signaling pathways. However, the specific activities of Bcl-x(L) at mitochondria and the endoplasmic reticulum(More)
