      Background InformationThe proto-oncogene Met (c-Met, HGF/SF Receptor, HGFR) is a receptor tyrosine kinase that is activated upon Hepatocyte Growth Factor (HGF) binding. This stimulates the autophosphorylation on Tyr1234/Tyr1235 which leads to pleiotropic downstream signaling events in epithelial cells that stimulate multiple cellular processes including cell proliferation, growth, differentiation, cell migration/ invasion, and tumorigenesis. These effects are mediated by SH2 domain-containing proteins that bind to the C-terminal tail of c-Met. Chronic stimulation of Met on cancer cells is thought to play a role in metastasis and dysregulation of c-Met activity is directly associated with oncogenesis, making it an important cancer target.

      Entrez Gene Number
      Entrez Gene SummaryThe proto-oncogene MET product is the hepatocyte growth factor receptor and encodes tyrosine-kinase activity. The primary single chain precursor protein is post-translationally cleaved to produce the alpha and beta subunits, which are disulfide linked to form the mature receptor. Various mutations in the MET gene are associated with papillary renal carcinoma. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq].

      UniProt Number
      UniProt SummaryFUNCTION: Receptor for hepatocyte growth factor and scatter factor. Has a tyrosine-protein kinase activity.

      Catalytic activity ATP + a [protein]-L-tyrosine = ADP + a [protein]-L-tyrosine phosphate.

      SUBUNIT:Heterodimer formed of an alpha chain (50 kDa) and a beta chain (145 kDa) which are disulfide linked. Binds PLXNB1 and GRB2. 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.

      LOCATION: Single-pass type I membrane protein.

      DOMAIN:The kinase domain is involved in SPSB1 binding.

      DISEASE: Activation of MET after rearrangement with the TPR gene produces an oncogenic protein.

      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 hereditary papillary renal carcinoma (HPRC) [MIM:605074]; also known as papillary renal cell carcinoma 2 (RCCP2). HPRC is a form of inherited kidney cancer characterized by a predisposition to develop multiple, bilateral papillary renal tumors. The pattern of inheritance is consistent with autosomal dominant transmission with reduced penetrance.

      Genetic variations in MET may be associated with susceptibility to autism type 1B (AUTS1B) [MIM:608636]. Autism is a neurodevelopmental disorder characterized by disturbance in language, perception and socialization. The disorder is classically defined by a triad of limited or absent verbal communication, a lack of reciprocal social interaction or responsiveness, and restricted, stereotypical, and ritualized patterns of interests and behavior.

      SIMILARITIES: Belongs to the protein kinase superfamily. Tyr protein kinase family.

      Contains 3 IPT/TIG domains.

      Contains 1 protein kinase domain.

      Contains 1 Sema domain.
