Bcl-xL promotes metastasis independent of its anti-apoptotic activity
Bcl-xL suppresses mitochondria-mediated apoptosis and is frequently overexpressed in cancer to promote cancer cell survival. Bcl-xL also promotes metastasis. However, it is unclear whether this metastatic function is dependent on its anti-apoptotic activity in the mitochondria. Here we demonstrate that Bcl-xL promotes metastasis independent of its anti-apoptotic activity. We show that apoptosis...

Characterization of the anti-apoptotic mechanism of Bcl-B.
Bcl-B protein is an anti-apoptotic member of the Bcl-2 family protein that contains all the four BH (Bcl-2 homology) domains (BH1, BH2, BH3 and BH4) and a predicted C-terminal transmembrane domain. Our previous results showed that Bcl-B binds Bax and suppresses apoptosis induced by over-expression of Bax; however, Bcl-B does not bind or suppress Bak. To explore the molecular basis for the diffe...
متن کاملReconstitution of the Anti-Apoptotic Bcl-2 Protein into Lipid Membranes and Biophysical Evidence for Its Detergent-Driven Association with the Pro-Apoptotic Bax Protein
The anti-apoptotic B-cell CLL/lymphoma-2 (Bcl-2) protein and its counterpart, the pro-apoptotic Bcl-2-associated X protein (Bax), are key players in the regulation of the mitochondrial pathway of apoptosis. However, how they interact at the mitochondrial outer membrane (MOM) and there determine whether the cell will live or be sentenced to death remains unknown. Competing models have been prese...
متن کاملThe Anti-Apoptotic Bcl-xL Protein, a New Piece in the Puzzle of Cytochrome C Interactome
A structural model of the adduct between human cytochrome c and the human anti-apoptotic protein Bcl-x(L), which defines the protein-protein interaction surface, was obtained from solution NMR chemical shift perturbation data. The atomic level information reveals key intermolecular contacts identifying new potentially druggable areas on cytochrome c and Bcl-x(L). Involvement of residues on cyto...
