Descriptor proteína adaptadora GRB2
Entry term(s) proteína 2 enlazada al receptor de factores de crecimiento
proteína 2 unida al receptor de factores de crecimiento
Scope note: Proteína adaptadora de transducción de señales que relaciona señales extracelulares con el SISTEMA DE SEÑALIZACIÓN DE LAS MAP CINASAS. La proteína Grb2 se asocia con el RECEPTOR DEL FACTOR DE CRECIMIENTO EPIDÉRMICO y con los RECEPTORES DEL FACTOR DE CRECIMIENTO DERIVADO DE PLAQUETAS por medio de su DOMINIO SH2. Se une también al HIJO DE LAS PROTEÍNAS SEVENLESS y las transloca por sus DOMNIOS SH3 para activar la PROTEÍNA PROTOONCOGÉNICA P21(RAS).

Scope note: 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).

GRB2 Adaptor Protein - Preferred
Concept UI M0204531
Scope note 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).

GRB2 Adaptor Protein, Grb3-3 Isoform - Narrower
Concept UI M0204529
Scope note 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.
