Figure 3.
Anti-GABARAP (8H5) antibody detects YFP-GABARAP, but not YFP-GABARAPL1 and CFP-GABARAPL2 in immunofluorescence. HAP1 GABARAP KO cells were transfected with YFP-GABARAP and YFP-empty vector (A) or YFP-GABARAPL1 and CFP-GABARAPL2, respectively (B). After 48 h cells were incubated for 3 h with 100 nM Bafilomycin A1 (BafA1) in growth factor depleted medium (w/o FCS). Fixed cells (4% PFA) were immunolabeled with anti-GABARAP (8H5) antibody. Colocalization of GABARAP (green) and YFP (red) is indicated by yellow puncta. Nuclei were counterstained with DAPI.
