• General notes

  
  

  Binding of scatter factor (SF)/hepatocyte growth factor (HGF) to the c Met receptor tyrosine kinase (RTK) triggers receptor dimerization and phosphorylation on multiple residues within the juxtamembrane, catalytic core and cytoplasmic tail domains, thereby regulating receptor internalization, catalytic activity and multisubstrate docking. c Met contains three tyrosines (Tyr-xx- x-Tyr-Tyr motif) within the activation loop of the catalytic domain. This is also seen with the insulin receptor, insulin-like growth factor receptor (IGF1) receptor and nerve growth factor (NGF) receptors/Trks, for which phosphorylation of all three tyrosines is required for full activation. With c Met (and the related family member, RON) phosphorylation of tyrosines 1234 and 1235 has been shown to be important in receptor activation. Activation of the c Met receptor results in binding and/or phosphorylation of many intracellular signaling proteins including multiple adaptor proteins (e.g., Grb2, Shc, Cbl, Crk, cortactin, paxillin, and GAB1), and a variety of other signal transducers (e.g., PI 3-kinase, FAK, Src, Erk1&2, JNK, PLC-ã, and STAT3).

Properties

• FormLiquid
• Storage instructionsShipped at 4°C. Upon delivery aliquot and store at -20°C or -80°C. Avoid repeated freeze / thaw cycles.
• Storage bufferPreservative: 0.05% Sodium Azide
  Constituents: 50% Glycerol, PBS, 1mg/ml BSA
• Concentration information loading...
• PurityImmunogen affinity purified
• Purification notesThe antibody has been negatively preadsorbed using a non-phosphopeptide corresponding to the site of phosphorylation to remove antibody that is reactive with non-phosphorylated c-Met protein. The final product is generated by affinity chromatography using a c Met-derived peptide that is phosphorylated at tyrosines 1230, 1234, 1235.

Applications

Target

• FunctionReceptor for hepatocyte growth factor and scatter factor. Has a tyrosine-protein kinase activity. Functions in cell proliferation, scattering, morphogenesis and survival.
• Involvement in diseaseNote=Activation of MET after rearrangement with the TPR gene produces an oncogenic protein.
  Note=Defects in MET may be associated with gastric cancer.
  Defects in MET are a cause of hepatocellular carcinoma (HCC) [MIM:114550].
  Defects in MET are a cause of renal cell carcinoma papillary (RCCP) [MIM:605074]. It is a subtype of renal cell carcinoma tending to show a tubulo-papillary architecture formed by numerous, irregular, finger-like projections of connective tissue. Renal cell carcinoma is a heterogeneous group of sporadic or hereditary carcinoma derived from cells of the proximal renal tubular epithelium. It is subclassified into common renal cell carcinoma (clear cell, non-papillary carcinoma), papillary renal cell carcinoma, chromophobe renal cell carcinoma, collecting duct carcinoma with medullary carcinoma of the kidney, and unclassified renal cell carcinoma.
  Note=A common allele in the promoter region of the MET shows genetic association with susceptibility to autism in some families. Functional assays indicate a decrease in MET promoter activity and altered binding of specific transcription factor complexes.
  Note=MET activating mutations may be involved in the development of a highly malignant, metastatic syndrome known as cancer of unknown primary origin (CUP) or primary occult malignancy. Systemic neoplastic spread is generally a late event in cancer progression. However, in some instances, distant dissemination arises at a very early stage, so that metastases reach clinical relevance before primary lesions. Sometimes, the primary lesions cannot be identified in spite of the progresses in the diagnosis of malignancies.

  Western blot - Anti-Met (c-Met) (phospho Y1230 + Y1234 + Y1235) antibody (ab5662)
  Peptide Competition: Extracts prepared from 293T cells left unstimulated (1) or stimulated with HGF (2-5) were resolved by SDS-PAGE on a 10% polyacrylamide gel and transferred to PVDF. Membranes were blocked with a 5% BSA-TBST buffer overnight at 4°C, then were incubated with the ab5662 antibody, following prior incubation with: no peptide (1, 2), the non-phosphopeptide corresponding to the immunogen (3), a generic phosphotyrosine-containing peptide (4), or, the phosphopeptide immunogen (5). After washing, membranes were incubated with goat F(ab’)2 antirabbit IgG HRP conjugate and bands were detected using the Pierce SuperSignal method. The data show that only the phosphopeptide corresponding to c Met [pYpYpY1230/1234/1235] block the antibody signal, demonstrating the specificity of the antibody. Note: There are three isoforms of c Met, two of which are recognized by this antibody.
