Nuclei were stained with DAPI (blue) on the MERGE image. (C) Immunoblots show MET ubiquitylation in presence of HGF (40 ng/ml, 10 min) in HEK cells in different experimental conditions. Cells were transfected, as indicated, with expression vectors for histidine-tagged ubiquitin (His-Ub) and MET. His-Ub crosslinked forms of MET were purified (IP: His) and the immunoblot of MET showed MET ubiquitylation. The immunoblot of MET (bottom panel) was performed in parallel to verify the amounts of MET protein engaged in His-Ub purifications. The immunoblot of UBTD1 shows the level of siRNA depletion. (D) Immunoblot and quantification of receptors. The immunoblot of UBTD1 shows the level of siRNA depletion. (E) mRNA quantification of receptors. mRNA of UBTD1 shows the level of siRNA depletion.
