NCBI and Uniprot Product Information
NCBI Description
The protein encoded by this gene binds the epidermal growth factor receptor and contains one SH2 domain and two SH3 domains. Its two SH3 domains direct complex formation with proline-rich regions of other proteins, and its SH2 domain binds tyrosine phosphorylated sequences. This gene is similar to the Sem5 gene of C.elegans, which is involved in the signal transduction pathway. Two alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2008]
Uniprot Description
Function: Adapter protein that provides a critical link between cell surface growth factor receptors and the Ras signaling pathway. Ref.1 Ref.3 Ref.54Isoform 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. Ref.1 Ref.3 Ref.54
Subunit structure: Associates with activated Tyr-phosphorylated EGF receptor/EGFR and PDGF receptors via its SH2 domain. Also associates to other cellular Tyr-phosphorylated proteins such as SIT1, IRS1, IRS4, SHC and LNK; probably via the concerted action of both its SH2 and SH3 domains. It also seems to interact with RAS in the signaling pathway leading to DNA synthesis. Binds to and translocates the guanine nucleotide exchange factors SOS. Interacts with phosphorylated TOM1L1 and MET. Interacts with the phosphorylated C-terminus of SH2B2. Interacts with phosphorylated SIT1, LAX1, LAT, LAT2 and LIME1 upon TCR and/or BCR activation. Interacts with NISCH, PTPNS1, REPS2 and the syntrophin SNTA1. Interacts with REPS1 and PIK3C2B via its SH3 domains

Interacts with PTK2B/PYK2 (tyrosine phosphorylated). Isoform 1 interacts with SCIMP. Interacts with PLCG1, LAT and THEMIS upon TCR activation in thymocytes

Product Notes
The GRB2 grb2 (Catalog #AAA6419161) is an Antibody produced from Rabbit and is intended for research purposes only. The product is available for immediate purchase. The GRB2 (Growth Factor Receptor-Bound Protein 2, ASH, Abundant Src Homology, Grb3-3, MST084, NCKAP2, MSTP084, EGFRBP-GRB2) (Biotin) reacts with Human, Mouse, Rat and may cross-react with other species as described in the data sheet. AAA Biotech's GRB2 can be used in a range of immunoassay formats including, but not limited to, Immunohistochemistry (IHC), Western Blot (WB). IHC: 1:50-1:200 WB: 1:500-1:2000 Applications are based on unconjugated antibody. Researchers should empirically determine the suitability of the GRB2 grb2 for an application not listed in the data sheet. Researchers commonly develop new applications and it is an integral, important part of the investigative research process. It is sometimes possible for the material contained within the vial of "GRB2, Polyclonal Antibody" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.Precautions
