Structural model of complex of Bcl-w protein with Bid BH3-peptideStructural model of complex of Bcl-w protein with Bid BH3-peptide
Structural highlights
Function[B2CL2_HUMAN] Promotes cell survival. Blocks dexamethasone-induced apoptosis. Mediates survival of postmitotic Sertoli cells by suppressing death-promoting activity of BAX.[1] [BID_HUMAN] The major proteolytic product p15 BID allows the release of cytochrome c (By similarity). Isoform 1, isoform 2 and isoform 4 induce ICE-like proteases and apoptosis. Isoform 3 does not induce apoptosis. Counters the protective effect of Bcl-2.[2] Evolutionary Conservation Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf. Publication Abstract from PubMedA peptide corresponding to the BH3 region of the proapoptotic protein, BID, could be bound in the cleft of the antiapoptotic protein, BCL-w. This binding induced major conformational rearrangements in both the peptide and protein components of the complex and led to the displacement and unfolding of the BCL-w C-terminal alpha-helix. The structure of BCL-w with a bound BID-BH3 peptide was determined using NMR spectroscopy and molecular docking. These studies confirmed that a region of 16 residues of the BID-BH3 peptide is responsible for its strong binding to BCL-w and BCL-x(L). The interactions of BCL-w and the BID-BH3 peptide complex with dodecylphosphocholine micelles were characterized and showed that the conformational change of BCL-w upon lipid binding occurred at the same time as the release and unfolding of the BH3 peptide.
