SOLUTION STRUCTURE OF A PRO-APOPTOTIC PROTEIN BAX
Contents |
Overview
Apoptosis is stimulated by the insertion of Bax from the cytosol into mitochondrial membranes. The solution structure of Bax, including the putative transmembrane domain at the C terminus, was determined in order to understand the regulation of its subcellular location. Bax consists of 9 alpha helices where the assembly of helices alpha1 through alpha 8 resembles that of the apoptosis inhibitor, Bcl-x(L). The C-terminal alpha 9 helix occupies the hydrophobic pocket proposed previously to mediate heterodimer formation and bioactivity of opposing members of the Bcl-2 family. The Bax structure shows that the orientation of helix alpha 9 provides simultaneous control over its mitochondrial targeting and dimer formation.
Disease
Known diseases associated with this structure: Colorectal cancer OMIM:[600040], T-cell acute lymphoblastic leukemia OMIM:[600040]
