NMR STRUCTURE OF THE FYN SH2 DOMAIN COMPLEXED WITH A PHOSPHOTYROSYL PEPTIDE, MINIMIZED AVERAGE STRUCTURE
Overview
BACKGROUND: SH2 domains are found in a variety of signal transduction, proteins; they bind phosphotyrosine-containing sequences, allowing them to, both recognize target molecules and regulate intramolecular kinase, activity. Fyn is a member of the Src family of tyrosine kinases that are, involved in signal transduction by association with a number of membrane, receptors. The kinase activity of these signalling proteins is modulated, by switching the binding mode of their SH2 and SH3 domains from, intramolecular to intermolecular. The molecular basis of the signalling, roles observed for different Src family members is still not well, understood; although structures have been determined for the SH2 domains, of other Src family molecules, this is the first structure of the Fyn SH2, domain. ...
