TOM20-mediated transfer of Bcl2 from ER to MAM and mitochondria upon induction of apoptosis

• Billy Bennett

On this work, we have now explored the subcellular localization of Bcl2, a significant antiapoptotic protein. In U251 glioma cells, we discovered that Bcl2 is localized primarily within the ER and is translocated to MAM and mitochondria upon induction of apoptosis; this mitochondrial switch was not restricted to the demonstrator cell line, even when cell-specific…
