TGFRI and TGFRII association in fibulin-6 KD cells upon TGF-beta stimulus.scr siRNA or fibulin-6 siRNA transfected nCF, after TGF-beta stimulation are subjected to (a) FACS analysis. No difference in the amount of TGF betaRI and TGF betaRII on the surface of control and fibulin-6 KD cells was observed. (b) Immuno-precipitation of TGFRII from cell lysates of scr transfected and TGF-beta stimulated cells, shows more accumulation of TGFRI after western blotting compared to non TGF-beta treated nCF. (c) Immuno-precipitation of TGFRII followed by WB for TGFRI from cell lysates of scr transfected or fibulin-6 KD cells after TGF-beta stimulation display reduced association of receptors in fibulin-6 KD condition. The control input lanes shows no difference and IgG control is also clean (n = 4, p < 0.05). (d) Phosphorylation status of TGFRI was analyzed by western blot using phospho-TGFRI specific antibody. Densitometric analysis of western blot display decreased phosphorylation of TGFRI in fibulin-6 KD cells after TGF-beta stimulation compared to control cells (n = 5, p < 0.01, nonparametric Mann-Whitney U test).

Background: TGF-beta RI/ALK-5

Most cell types express three sizes of receptors for TGF-beta. These are designated Type I (53 kDa), Type II (70-85 kDa), and Type III (250-350 kDa). The Type III receptor, a proteoglycan that exists in membrane-bound and soluble forms, binds TGF-beta 1, TGF-beta 2, and TGF-beta 3 but does not appear to be involved in signal transduction. The Type II receptor is a membrane-bound serine/threonine kinase that binds TGF-beta 1 and TGF-beta 3 with high affinity and TGF-beta 2 with a much lower affinity. The Type I receptor, originally known as ALK-5 (Activin receptor‑like kinase) is also a membrane-bound serine/threonine kinase that apparently requires the presence of the Type II receptor to bind TGF-beta. Current evidence suggests that signal transduction requires the cytoplasmic domains of both the Type I and Type II receptors.
