Met, a high affinity receptor for hepatocyte growth factor (HGF; also known as scatter factor), is a disulfide-linked heterodimer made of 45kD alpha and 145kD beta-subunits (1,2).
The alpha-subunit and the amino-terminal region of beta-subunit form the extracellular domain.
The remainder of the beta-chain spans the plasma membrane and contains a cytoplasmic region with tyrosine kinase activity.
Interaction of Met with HGF results in autophosphorylation at multiple tyrosines, which recruit several downstream signaling components, including Gab1, c-Cbl and PI3 kinase (3) and is critical for all of its known biological functions.
Phosphorylation of Tyr1234/1235 in the Met kinase domain is critical to kinase activation.
Phosphorylation of Tyr1349 in the Met cytoplasmic domain provides a direct binding site for Gab1 (4).
Altered Met levels and/or tyrosine kinase activities were found in different tumors, especially in renal, colon and breast cancers.
Thus, Met is an attractive therapeutic target and cancer diagnostic (5).
