MeSH definition : A signal transducing adaptor protein that links extracellular signals to the MAP KINASE
SIGNALING SYSTEM. Grb2 associates with activated EPIDERMAL GROWTH FACTOR RECEPTOR
and PLATELET-DERIVED GROWTH FACTOR RECEPTORS via its SH2 DOMAIN. It also binds to
and translocates the SON OF SEVENLESS PROTEINS through its SH3 DOMAINS to activate
PROTO-ONCOGENE PROTEIN P21(RAS).;
