Abstract

The Bcl-2 family proteins plays a central role in apoptosis. The pro- or anti-apoptotic activities of Bcl-2 family are dependent on the Bcl-2 homology (BH) regions. Bcl-rambo, a new pro-apoptotic member, is unusual in that its pro-apoptotic activity is independent of its BH domains. However, the mechanism underlying Bcl-rambo-induced apoptosis is largely unknown. Mitochondrial localization is indispensable for the pro-apoptotic function of Bcl-rambo. Bcl-rambo interacts physically with the adenine nucleotide translocator (ANT), suppresses the ADT/ATP-dependent translocation activity of ANT. Collectively, our data indicate Bcl-rambo is a pro-apoptotic member of the Bcl-2 family, induces the permeability transition via interaction with ANT.
