This domain is connected to the transmembrane helix through four immunoglob ulinplexintranscription domains, which are related to immunoglobulin like domains and are found in integrins, The ligand for c MET was identified by two independent studies as both a motility element plus a scatter element for hepatocytes, and this element was later identified to become exactly the same molecule:

The a chain includes an N terminal hair pin loop followed by four kringle domains.Physiologically, c MET is responsible for the cell scattering phenotype, as 1st demonstrated with MDCK cells handled with HGF.

Through embryogenesis, this motility func tion of c MET is vital for the long range migration of skeletal muscle progenitor cells. As well, altered pla cental advancement in Hgf and MET knockout mice is responsible for the death of these animals in utero. HGF/c MET signaling The complex phenotype that final results from c MET signaling includes quite a few molecular events, which have been described in detail in preceding reviews.

These two tyrosines type a tandem SH2 recognition motif unique to c MET . phospholipase Cg and v src sar coma viral oncogene homolog Src homol ogy domain containing 5 inositol phosphatase and the transcription element signal transducer and activator of transcrip tion Furthermore, special to c MET is its association with the adaptor protein GRB2 associated binding protein 1 a multi adaptor protein that, once bound to and phosphorylated by c MET, creates binding websites for additional downstream adaptors.

Added tyrosines also can contribute to c MET signaling. When Y1313 is phosphorylated, it binds and activates PI3K, which almost certainly promotes cell viability and motility. Furthermore, Y1365 regulates cell morphogenesis when phosphorylated.

For activation from the Mitogen activated protein kinase cascades, c MET activation stimulates the activity from the rat sarcoma viral oncogene homolog guanine nucleotide exchanger Son of Sevenless through binding with SHC and GRB2 top to the activation of RAS.

Src homology 2 domain containing phosphatase 2 also can link c MET signaling to the MAPK cas cade, as sequestration of SHP2 to GAB1 is responsible for extending the duration of MAPK phosphorylation. STAT3 has also been implicated in transformation, despite the fact that its proposed mecha nism is controversial. The direct binding of STAT3 to c MET final results in STAT3 phosphory lation, dimerization and its translocation to the nucleus.

However, other reports identified that, despite the fact that it truly is required for c MET mediated tumorigenesis, it has no effect on pro liferation, invasion or branching morphogenesis. FAK is activated by means of phosphorylation by SRC loved ones kinases, which have been shown to associ ate directly with c MET. The c METSRCFAK interaction leads to cell migration and the promotion of anchorage inde pendent growth. Furthermore, SRC activation can positively feed back on c MET activation.

Negative regulation from the c MET receptor is vital for its tightly controlled activity, and may happen through a number of mechanisms.
