Figure Lengend Snippet: TMEM184B localizes to early and late endosomes in human cells. All images show HEK293T cells expressing FLAG-TMEM184B-GFP. DAPI (blue) marks the nucleus. Images represent single slices of human cells. A-D, images depicting localization of FLAG-TMEM184B-GFP to early endosomes (mCherry-Rab5, A), late endosomes (mCherry-Rab7, B), recycling endosomes (dsRed-Rab11, C), and lysosomes (LAMP1+CTSD, D). White arrows highlight overlapping puncta. Scale bars = 2 μm. n = 45-60 cells per marker, imaged over 3 sessions each. E, Fraction of merged puncta over total TMEM184B puncta area. F, Fraction of merged puncta over the total red pixel area of endosomal markers. G, Fraction of merged puncta (TMEM184B + LAMP1 + CTSD) over total TMEM184B pixel area. H, Fraction of merged puncta over the total red pixel area (LAMP1 + CTSD) of lysosomal markers. Error bars represent SEM.
