Ins(1,4,5)P3-mediated calcium signals and apoptosis: is there a role for Bcl-2?
2003
In this review we speculate that the anti-apoptotic protein Bcl-2 may regulate calcium signals involved in mediating cell death. Evidence that Ins(1,4,5) P 3 -mediated calcium release from the endoplasmic reticulum triggers apoptosis in response to diverse signals is summarized. Also, we review evidence that Bcl-2 regulates calcium release from the endoplasmic reticulum, and speculate that Bcl-2 may interact either functionally or physically with Ins(1,4,5) P 3 receptors to modulate calcium signals that determine life or death decisions.
