SDC1 bond to TGM2, and transported from cell surface to intracellular. (A) Immunofluorescence images of subcellular location of SDC1 (red) and TGM2 (green) proteins in GBM cells at 2–12 h after 4 Gy IR. DAPI-stained nuclei are blue. Scale bars: 10 μm. (B) Immunoblots of Co-IP assay that verified the binding of SDC1 to TGM2. (C) Schematic diagram depicting wild-type and fragmental SDC1 proteins. (D) Co-IP assay was used to validate the binding of TGM2 to wild-type SDC1 or SDC1 fragments.
