Fig. 5: YIPF2 inhibits the interaction between TNFRSF10B and RAB8.

a H1299 cells were transfected with pcDNA3.1 or pcDNA3.1-Flag-TNFRSF10B (short isoform) plasmids. Then the co-IP assays were carried out with Flag antibody and the co-eluted proteins were detected by western blot assays with Flag and YIPF2 antibodies. b, c H1792 cells were transfected with pEGFP-N1 or pEGFP-N1-YIPF2 plasmids. Then the co-IP assays were carried out with GFP antibody and the co-eluted proteins were detected by western blot assays with GFP, TNFRSF10B (b) and RAB8 (c) antibodies. d H1792 cells were transfected with pEGFP-N1 or pEGFP-N1-RAB8 plasmids. Then the co-IP assays were carried out with GFP antibody and the co-eluted proteins were detected by western blot assays with GFP, and TNFRSF10B antibodies. e Cell lysates were prepared from H1792 cells transiently co-expressing pEGFP-N1-RAB8 and pcDNA3.1-YIPF2. The co-IP assays were carried out with GFP antibody and the co-eluted proteins were detected by western blot assays with YIPF2, GFP and TNFRSF10B antibodies. f Schematic illustration showing that YIPF2 promotes PEM-mediated apoptosis via enhancing TNFRSF10B recycling to plasma membrane in NSCLC cells.
