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). Grb3-3 is a natural isoform of GRB2 PROTEIN with a deletion in the SH2 DOMAIN. It acts as a dominant negative protein over GRB2, suppressing proliferative signals. It has also been implicated in APOPTOSIS.
