c-Met (MET, receptor hepatocitnog faktora rasta, HGFR),[1][2]protein je koji je kod ljudi kodiran MET genom (MET proto-onkogena receptorska tirozinska kinaza). U ranijem razdoblju istraživačkog procesa takođe je nazivan MNNG HOS transformišući gen. Ova protein deluje kao tirozinska kinaza.[3] Primarni jednolančani prekursorni protein se posttranslaciono preseca i time se formiraju alfa i beta podjedinica, koje se disulfidno vezuju pri formiraju krajnjeg oblika receptora.
MET je membranski receptor koji je esencijalan za embrionsko razviće i zarastanje rana. Hepatocitni faktor rasta (HGF) je jedini poznati ligand MET receptora. MET je normalno izražen u ćelijama epitelnog porekla, dok je izražavanje HGF ograničeno na ćelije mesenhimalnog porekla. Nakon HGF stimulacije, MET indukuje nekoliko bioloških responsa koji kolektivno formiraju program poznat kao invazivni rast.
