GRB2 (Growth factor receptor-bound protein 2) is a gene. The public catalogues list it as a drug target, and clinical evidence ties its variants to diagnosis, prognosis or drug response. Tied to Leukaemia, Myeloproliferative neoplasms and Chronic myeloid leukaemia. This dossier gathers the 0 products (0 approved), 0 trials, 0 pathways and 0 resistance routes in the corpus that involve it, with external identifiers so it can be joined to UniProt, ChEMBL, Open Targets and the rest of biology.
Non-enzymatic adapter protein that plays a pivotal role in precisely regulated signalling cascades from cell surface receptors to cellular responses, including signalling transduction and gene expression. Thus, participates in many biological processes including regulation of innate and adaptive immunity, autophagy, DNA repair or necroptosis. Controls signalling complexes at the T-cell antigen receptor to facilitate the activation, differentiation, and function of T-cells. Mechanistically, engagement of the TCR leads to phosphorylation of the adapter protein LAT, which serves as docking site for GRB2. In turn, GRB2 establishes a a connection with SOS1 that acts as a guanine nucleotide exchange factor and serves as a critical regulator of KRAS/RAF1 leading to MAPKs translocation to the nucleus and activation. Functions also a role in B-cell activation by amplifying Ca(2+) mobilisation and activation of the ERK MAP kinase pathway upon recruitment to the phosphorylated B-cell antigen receptor (BCR). Location: Nucleus; Cytoplasm; Endosome; Golgi apparatus (UniProt). Locus 17q25.1 (HGNC).
