| + | [https://www.uniprot.org/uniprot/B2CL1_HUMAN B2CL1_HUMAN] Potent inhibitor of cell death. Inhibits activation of caspases (By similarity). Appears to regulate cell death by blocking the voltage-dependent anion channel (VDAC) by binding to it and preventing the release of the caspase activator, CYC1, from the mitochondrial membrane. Also acts as a regulator of G2 checkpoint and progression to cytokinesis during mitosis.<ref>PMID:19917720</ref> <ref>PMID:21840391</ref> Isoform Bcl-X(S) promotes apoptosis.<ref>PMID:19917720</ref> <ref>PMID:21840391</ref> | ||

| + | Bcl-xL is a major inhibitor of apoptosis, a fundamental homeostatic process of programmed cell death that is highly conserved across evolution. Because it plays prominent roles in cancer, Bcl-xL is a major target for anticancer therapy and for studies aimed at understanding its structure and activity. Although Bcl-xL is active primarily at intracellular membranes, most studies have focused on soluble forms of the protein lacking both the membrane-anchoring C-terminal tail and the intrinsically disordered loop, and this has resulted in a fragmented view of the protein's biological activity. Here, we describe the conformation of full-length Bcl-xL. Using NMR spectroscopy, molecular dynamics simulations, and isothermal titration calorimetry, we show how the three structural elements affect the protein's structure, dynamics, and ligand-binding activity in both its soluble and membrane-anchored states. The combined data provide information about the molecular basis for the protein's functionality and a view of its complex molecular mechanisms. | ||
