Quantitation of autoinhibitory defects in pathogenic SHP2 mutants by differential scanning fluorimetry.

Abstract excerpt

Src-homology-2-domain-containing protein tyrosine phosphatase-2 (SHP2) is a signaling enzyme whose activity is governed by an equilibrium between autoinhibited and activated states. Regulation of SHP2 activity is critical for cellular homeostasis, and mutations that alter its autoregulatory equilibrium cause cancers and developmental disorders. Several methods for assessing the strength of autoinhibitory...
