Correlated motions and propagation of the effect of a local conformational change in the transmembrane helix of the c-erb B2 encoded protein and its V659E mutant, studied by molecular dynamics simulations.

Abstract excerpt

A detailed study of the dynamical behavior of the 29-residue peptide including the transmembrane domain of p185c-erbB2 oncogene-encoded protein and of its V659E mutant is presented. In a first part of this work we analyse equal time correlation coefficients between the backbone dihedral angle fluctuations. Concerted motions are observed in the wild type transmembrane alpha-helix but not in the corresponding V659E...
