Determining folding and binding properties of the C-terminal SH2 domain of SHP2.

ABSTRACT: SH2 domains are a class of protein-protein interaction modules with the function to recognize and bind sequences characterized by the presence of a phosphorylated tyrosine. SHP2 is a protein phosphatase involved in the Ras-ERK1/2 signaling pathway that possess two SH2 domains, namely, N-SH2 and C-SH2, that mediate the interaction of SHP2 with various partners and determine the regulation of its catalytic activity. One of the main interactors of the SH2 domains of SHP2 is Gab2, a scaffolding protein with critical role in determining cell differentiation. Despite their key biological role and the importance of a correct native fold to ensure it, the mechanism of binding of SH2 domains with their ligands and the determinants of their stability have been poorly characterized.
