Hepatocyte growth factor receptor (HGF receptor) [5] [6] is a protein that in humans is encoded by the MET gene.The protein possesses tyrosine kinase activity. [7] 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.

These adaptor proteins link RTK activation to downstream signal transduction pathways, such as the MAP kinase signalling cascade. [2] An example of a vital signal transduction pathway involves the tyrosine kinase receptor, c-met, which is required for the survival and proliferation of migrating myoblasts during myogenesis. A lack of c-met ...
c-Met stimulates cell scattering, invasion, protection from apoptosis and angiogenesis. [4] c-Met is a receptor tyrosine kinase, [5] which can cause a wide variety of different cancers, such as renal, gastric and small cell lung carcinomas, central nervous system tumours, as well as several sarcomas [6] when its activity is
Such a pathway can trigger the assembly of new molecules, such as a fat or protein. Pathways can also turn genes on and off, or spur a cell to move. [1] Some of the most common biological pathways are involved in metabolism, the regulation of gene expression and the transmission of signals. Pathways play a key role in advanced studies of genomics.
Cell signaling research involves studying the spatial and temporal dynamics of both receptors and the components of signaling pathways that are activated by receptors in various cell types. [55] [56] Emerging methods for single-cell mass-spectrometry analysis promise to enable studying signal transduction with single-cell resolution. [57]
Secondary messenger systems can be synthesized and activated by enzymes, for example, the cyclases that synthesize cyclic nucleotides, or by opening of ion channels to allow influx of metal ions, for example Ca 2+ signaling. These small molecules bind and activate protein kinases, ion channels, and other proteins, thus continuing the signaling ...
The COMT protein is coded by the gene COMT.The gene is associated with allelic variants. The best-studied is Val 158 Met. [15] Others are rs737865 and rs165599 that have been studied, e.g., for association with personality traits, [21] response to antidepressant medications, [22] and psychosis risk associated with Alzheimer's disease.
