Background: TGF-β receptor types are type I receptor (TGFB-RI, TβR1 kinase or ALK5) belongs to the class of transmembrane serine/threonine protein kinases. Ligand (transforming growth factor-β, TGF-β) binding assembles a complex consisting of TβRII (signal-activating receptor) and TβR1 (signal-propagating receptor). TβRII phosphorylates TβR1, and activated kinase propagates the signal via phosphorylation of substrate SMAD proteins, SMAD2 and SMAD3. Activated SMAD protein complexes translocate to the nucleus and regulate transcriptional activation. TGF-β can also signal through Smad-independent signaling, including the PI3 kinase, MAPK, TRAF6-TAK1 and RhoA-Rock pathways e.g. by phosphorylation of ShcA proteins on tyrosine and serine. TGF-β signaling pathway has the dual role in both tumor suppression and tumor promotion and thus TGF-β is being evaluated as potential therapeutic target.
