产品介绍background:
c-Met, a member of the tyrosine kinase superfamily, is the receptor for hepatocyte growth factor, also known as scatter factor (HGF/SF). The mature c-Met protein is a disulfide-linked heterodimer with Mr=190 kDa composed of a heavily glycosylated alpha subunit that is completely extracellular in localization, and a beta subunit comprising an extracellular ligand binding domain, a single transmembrane domain, and a cytoplasmic tyrosine kinase domain. Cells expressing c-Met include epithelial cells, endothelial cells, blood cells of various types, and glomerular mesenchymal cells.
HGF/SF binding to c-Met stimulates receptor dimerization and the phosphorylation of numerous residues within the receptor’s cytoplasmic domain. Signaling proteins that are phosphorylated and/or localized in response to c-Met phosphorylation include: Grb2, Shc, Cbl, Crk, cortactin, paxillin, GAB1, PI3K, FAK, Src, Ras, ERK1 and 2, JNK, PLC gamma, AKT, and STAT3. HGF/SF stimulation of c-Met expressing cells enhances proliferation, migration, morphogenesis, and protease synthesis, characteristics that are associated with invasive cell phenotype. Many types of cancer exhibit sustained c-Met stimulation, overexpression, or mutation, including carcinomas of the colon, breast, ovary, lung, liver, prostate, thyroid, kidney, as well as melanomas and sarcomas. In addition to cancer studies, other research areas in which c-Met is under investigation include organogenesis, organ regeneration, angiogenesis and surgical wound healing.
Function:
Receptor tyrosine kinase that transduces signals from the extracellular matrix into the cytoplasm by binding to hepatocyte growth factor/HGF ligand. Regulates many physiological processes including proliferation, scattering, morphogenesis and survival. Ligand binding at the cell surface induces autophosphorylation of MET on its intracellular domain that provides docking sites for downstream signaling molecules. Following activation by ligand, interacts with the PI3-kinase subunit PIK3R1, PLCG1, SRC, GRB2, STAT3 or the adapter GAB1. Recruitment of these downstream effectors by MET leads to the activation of several signaling cascades including the RAS-ERK, PI3 kinase-AKT, or PLCgamma-PKC. The RAS-ERK activation is associated with the morphogenetic effects while PI3K/AKT coordinates prosurvival effects. During embryonic development, MET signaling plays a role in gastrulation, development and migration of muscles and neuronal precursors, angiogenesis and kidney formation. In *****s, participates in wound healing as well as organ regeneration and tissue remodeling. Promotes also differentiation and proliferation of hematopoietic cells.
Acts as a receptor for Listeria internalin inlB, mediating entry of the pathogen into cells.
Subunit:
Heterodimer made of an alpha chain (50 kDa) and a beta chain (145 kDa) which are disulfide linked. Binds PLXNB1. Interacts when phosphorylated with downstream effectors including STAT3, PIK3R1, SRC, PCLG1, GRB2 and GAB1. Interacts with SPSB1, SPSB2 and SPSB4 (By similarity). Interacts with INPP5D/SHIP1. When phosphorylated at Tyr-1356, interacts with INPPL1/SHIP2. Interacts with RANBP9 and RANBP10, as well as SPSB1, SPSB2, SPSB3 and SPSB4. SPSB1 binding occurs in the presence and in the absence of HGF, however HGF treatment has a positive effect on this interaction. Interacts with MUC20; prevents interaction with GRB2 and suppresses hepatocyte growth factor-induced cell proliferation. Interacts with GRB10.
Subcellular Location:
Membrane; Single-pass type I membrane protein.
Isoform 3: Secreted.
Tissue Specificity:
Expressed in normal hepatocytes as well as in epithelial cells lining the stomach, the small and the large intestine. Found also in basal keratinocytes of esophagus and skin. High levels are found in liver, gastrointestinal tract, thyroid and kidney. Also present in the brain.
Post-translational modifications:
Autophosphorylated in response to ligand binding on Tyr-1234 and Tyr-1235 in the kinase domain leading to further phosphorylation of Tyr-1349 and Tyr-1356 in the C-terminal multifunctional docking site.
Dephosphorylated by PTPRJ at Tyr-1349 and Tyr-1365.
Ubiquitinated. Ubiquitination by CBL regulates the receptor stability and activity through proteasomal degradation.
DISEASE:
Note=Activation of MET after rearrangement with the TPR gene produces an oncogenic protein.
Note=Defects in MET may be associated with gastric cancer.
Hepatocellular carcinoma (HCC) [MIM:114550]: A primary malignant neoplasm of epithelial liver cells. The major risk factors for HCC are chronic hepatitis B virus (HBV) infection, chronic hepatitis C virus (HCV) infection, prolonged dietary aflatoxin exposure, alcoholic cirrhosis, and cirrhosis due to other causes. Note=The disease is caused by mutations affecting the gene represented in this entry.
Renal cell carcinoma papillary (RCCP) [MIM:605074]: 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. Note=The disease is caused by mutations affecting the gene represented in this entry.
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.

Phospho-Met (Tyr1003)抗体（antibody,
Ab）是由效应B细胞（效应**B细胞）分泌，机体用于抵御外来物质，如病毒，**等抗原，结构呈“Y”字型的球状蛋白质，仅仅存在于脊椎动物的血液和B**细胞膜表面。凡是能够跟抗体结合的物质，均被称作抗原，因此对于抗抗体（能够结合抗体的抗体）来说，抗体本身也是一种抗原物质。
Phospho-Met (Tyr1003)抗体普通抗体重链和轻链的结构
重链结构：普通的**球蛋白具有2条重链（H链），分子量约为50kD,有μ、δ、γ、ε和α五种重链亚型，对应的**球蛋白名称分别为IgM、IgG、IgA、IgD和IgE。
轻链结构： 普通**球蛋白具有2条轻链（L链），分子质量约25kDa，有κ链和λ链两种亚型，这两种轻链决定了Ig的亚型类别（IgG1，IgG2，IgG3，IgG4）。一个天然的Ig分子两条轻链总是相同的，但在同一个体内可存在分别带有κ或λ链的抗体分子。不同种属生物体内两型轻链的比例不同，正常人血清**球蛋白κ链：λ链约为2：1，而在小鼠的比例为20：1。
2.2抗体Fab段和Fc段
IgG经木瓜蛋白酶酶切后裂解为2个完全相同的Fab段和1个Fc段,每个Fab段都为单价,可与抗原结合但不会再发生凝集反应；经胃蛋白酶酶切后裂解为1个完整F(ab)2片段和碎片化的Fc片段,F(ab’)2片段为双价,可同时结合两个抗原表位。Fab段为抗原结合片段（fragment of antigen binding，Fab），相当于抗体分子的两个臂，由一个完整的轻链和重链的VH和CH1结构域组成。Fc段为可结晶段（fragment crystallizable，Fc）相当于Ig的CH2和CH3结构域，是Ig与效应分子或者细胞相互作用的部位。Fab段包含完整的可变区，以及恒定区的CH1区域。Fc段仅指Ig恒定区CH2和CH3的区域，相当于Y字结构下面那一部分。
