WebDec 12, 2024 · However, the pore(s) that promotes MOMP in live cells or in conditions that do not activate BAX/BAK has not been identified. Because the voltage-dependent anion channel (VDAC) can oligomerize under oxidative stress conditions, and VDAC oligomers can form large MOM pores ( 5 ), we investigated whether VDAC could trigger MOMP in … WebBax and Bak are members of the Bcl-2 family and core regulators of the intrinsic pathway of apoptosis. Upon apoptotic stimuli, they are activated and oligomerize at the mitochondrial outer membrane (MOM) to mediate its permeabilization, which is considered a …

WebJun 19, 2024 · Nevertheless, it is likely that in the context of the cell, other proteins, like Bak or Drp1, and maybe lipids, also participate in MOM pores thereby modulating the features of Bax-mediated pores. Indeed, in the absence of Drp1, Bax continued to form large pores but cytochrome c release was hampered [ 76 ]. WebBim is a protein that activates Bax and Bak so that these proteins can each form potes in the outer mitochondrial membrane.
