Abstract: Bcl-2 family proteins generally have a proapoptotic or antiapoptotic role. In addition to their known roles at the mitochondria, Bcl-2 family proteins also influence signaling at the endoplasmic reticulum by binding to the inositol 1,4,5-trisphosphate receptor (IP3R), the most ubiquitous intracellular Ca2+ channel. Surprisingly, multiple Bcl-2 family proteins target different sites on the IP3R to elicit various effects on IP3R function, which suggests that the IP3R is an important hub for Bcl-2 family proteins in various physiological settings.
