Descrizione

Descrizione generale

Hepatocyte growth factor receptor (EC 2.7.10.1; UniProt P08581; also known as HGF receptor, HGF/SF receptor, Proto-oncogene c-Met, Scatter factor receptor, SF receptor, Tyrosine-protein kinase Met) is encoded by the MET (also known as AUTS9, HCC, RCCP) gene (Gene ID 4233) in human. HGF receptor or c-Met is initially produced as a 1390-a.a. precursor protein with an N-terminal signal peptide, postranslational proteolytic cleavage yields the mature tyrosine kinase receptor composed of an extracellular alpha chain (a.a. 25-307) linked via a disulfide bond to a transmembrane beta chain with an extracellular domain (a.a. 308-932), transmembrane helix (a.a. 933-955), and a cytoplasmic domain (a.a. 956-1390). The alpha-chain and the extracellular portion of beta-chain form the Sema domain that mediates receptor dimerization and ligand binding. The cytoplasmic portion of beta-chain contains the kinase domain (a.a. 1078-1345) and a C-terminal tail that contains a docking region (a.a. 1212-1390) for effector and adapter proteins essential for downstream signaling. Hepatocyte growth factor (HGF) is the only known c-Met ligand. HGF binding induces c-Met dimerization and autophosphorylation on Y1230, Y1234 and Y1235, leading to a conformation change and further phosphorylation on Y1349 and Y1356, making C-terminal tail docking region available for adaptor and signalling molecules. c-Met mediates a wide-range of biological activities, including cell proliferation, motility, angiogenesis and morphogenesis, and is an attractive target for cancer therapy. Aberrant c-Met activation/signalling promotes cancer cell proliferation and is associated with poor prognosis in various human cancers. Upregulated c-Met expression is also known to cause resistance against HER2, EGFR and B-RAF inhibitory drugs in cancer treatment.

Specificità

Clone seeMet 13 bound strongly to native c-Met by flow cytometry, while exhibiting low reactivity and specificity towards denatured c-Met by Western blotting (Wong, J.S., et al. (2013). Oncotarget. 4(7):1019-1036).

Immunogeno

His-tagged recombinant human c-Met alpha chain (Wong, J.S., et al. (2013). Oncotarget. 4(7):1019-1036).

Applicazioni

Detect Hepatocyte growth factor receptor using this mouse monoclonal Anti-c-Met, clone seeMet 13, Cat. No. MABS1916, validated for use in Flow Cytometry, Immunocytochemistry, Immunoprecipitation, and Inhibition studies.

Flow Cytometry Analysis: 0.2 µL from a representative lot detected c-Met immunoreactivity on the surface of one million SNU-5 cells.

Flow Cytometry Analysis: A representative lot immunostained live SNU-5 cells. A slight decrease in antibody immunoreactivity was observed when the temperature was dropped from 37°C to 4°C (Wong, J.S., et al. (2013). Oncotarget. 4(7):1019-1036).

Immunocytochemistry Analysis: A representative lot immunostained live SNU-5 cells. Indirect fluorescence labelling following subsequent cell fixation and permeabilization revealed increased antibody cytoplasmic internalization when antibody incubation was performed at 37°C than at 4°C (Wong, J.S., et al. (2013). Oncotarget. 4(7):1019-1036).

Immunoprecipitation Analysis: A representative lot immunoprecipitated c-Met from SNU-5 cell lysate (Wong, J.S., et al. (2013). Oncotarget. 4(7):1019-1036).

Inhibition Analysis: A representative lot prevented HGF-induced scatter of HaCaT cells. Clone seeMet 13 inhibited cell proliferation by blocking cell division without inducing apoptosis (Wong, J.S., et al. (2013). Oncotarget. 4(7):1019-1036).

Note: seeMet 13 exhibited low reactivity and specificity towards denatured c-Met by Western blotting. This monoclonal antibody is not recommended for Western blotting application (Wong, J.S., et al. (2013). Oncotarget. 4(7):1019-1036).
