Project description

We previously found that the anti-apoptotic protein Bcl-2, but not Bcl-Xl, binds to the central, modulatory domain of the inositol trisphosphate receptor through its BH4-domain, thereby inhibiting endoplasmic reticulum (ER) Ca2+ release and apoptosis. This project will explore novel functions of BH4-Bcl-2 and BH4-Bcl-Xl, focusing on the interactions with the ER ryanodine receptor and the mitochondrial voltage-dependent anion channel 1.
