GROWTH FACTOR RECEPTOR BINDING PROTEIN SH2 DOMAIN (HUMAN) COMPLEXED WITH A PHOSPHOTYROSYL DERIVATIVE
Structural highlights
FunctionGRB2_HUMAN Adapter protein that provides a critical link between cell surface growth factor receptors and the Ras signaling pathway.[1] [2] [3] Isoform 2 does not bind to phosphorylated epidermal growth factor receptor (EGFR) but inhibits EGF-induced transactivation of a RAS-responsive element. Isoform 2 acts as a dominant negative protein over GRB2 and by suppressing proliferative signals, may trigger active programmed cell death.[4] [5] [6] Evolutionary Conservation Check, as determined by ConSurfDB.

Publication Abstract from PubMedPrevious efforts in the search for molecules capable of blocking the associations between the activated tyrosine kinase growth factor receptors and the SH2 domain of Grb2 had resulted in the identification of 3-amino-Z-pTyr-Ac6c-Asn-NH2, a high-affinity and selective antagonist of this SH2 domain. In the present paper, we report the successful replacement of asparagine in this compound by a beta-amino acid mimetic, which brings us closer to our objective of identifying a Grb2-SH2 antagonist suitable for pharmacological investigations.
