Phospho-c-Met (Tyr1003) Antibody - #AF3128

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. May regulate cortical bone osteogenesis (By similarity).

(Microbial infection) Acts as a receptor for Listeria monocytogenes internalin InlB, mediating entry of the pathogen into cells.

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. Dephosphorylated by PTPN1 and PTPN2.

Ubiquitinated. Ubiquitination by CBL regulates MET endocytosis, resulting in decreasing plasma membrane receptor abundance, and in endosomal degradation and/or recycling of internalized receptors.

(Microbial infection) Tyrosine phosphorylation is stimulated by L.monocytogenes InlB. Tyrosine phosphorylation is maximal 10-20 minutes after treatment with InlB and disappears by 60 minutes. The phosphorylated residues were not identified.

Membrane>Single-pass type I membrane protein.

Secreted.

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. Expressed in metaphyseal bone (at protein level).

The kinase domain is involved in SPSB1 binding.

The beta-propeller Sema domain mediates binding to HGF.

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