Fig. 2: CISD2 and its role in MAMs.

CISD2 is expressed in the ER membrane and in the outer mitochondrial membranes. The protein resides in the MAMs where it could oligomerize. CISD2 interacts with BCL2 to regulate Ca2+ homeostasis and apoptosis. Finally, CISD2 interacts with Gimap5 to control the differentiation of adipocytes
