SHC PTB DOMAIN COMPLEXED WITH A TRKA RECEPTOR PHOSPHOPEPTIDE, NMR, MINIMIZED AVERAGE STRUCTURE
|
OverviewOverview
The nuclear magnetic resonance structure of the phosphotyrosine binding, (PTB) domain of Shc complexed to a phosphopeptide reveals an alternative, means of recognizing tyrosine-phosphorylated proteins. Unlike in SH2, domains, the phosphopeptide forms an antiparallel beta-strand with a, beta-sheet of the protein, interacts with a hydrophobic pocket through the, (pY-5) residue, and adopts a beta-turn. The PTB domain is structurally, similar to pleckstrin homology domains (a beta-sandwich capped by an, alpha-helix) and binds to acidic phospholipids, suggesting a possible role, in membrane localization.
