[https://www.uniprot.org/uniprot/MET_HUMAN MET_HUMAN] 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 adults, participates in wound healing as well as organ regeneration and tissue remodeling. Promotes also differentiation and proliferation of hematopoietic cells.<ref>PMID:1846706</ref> <ref>PMID:8182137</ref> <ref>PMID:15314156</ref>  Acts as a receptor for Listeria internalin inlB, mediating entry of the pathogen into cells.<ref>PMID:1846706</ref> <ref>PMID:8182137</ref> <ref>PMID:15314156</ref>

== Publication Abstract from PubMed ==
Two series of new analogues were designed by replacing the quinoline scaffold of our earlier lead 2 (zgwatinib) with quinoxaline and pyrido[2,3-d]pyrimidine frameworks. Moderate c-Met inhibitory activity was observed in the quinoxaline series. Among the pyrido[2,3-d]pyrimidine series, compounds 13a-c possessing an O-linkage were inactive, whilst the N-linked analogues 15a-c retained c-Met inhibitory potency. Highest activity was observed in the 3-nitrobenzyl analog 15b that showed an IC(50) value of 6.5nM. Further structural modifications based on this compound were undergoing.
