BAD-LAMP–dependent sorting of UNC93B1 to the endosomes. Immunofluorescence confocal microscopy of HeLa cells transfected with an eGFP-tagged BAD-LAMP fusion. BAD-LAMP-GFP (green) is sorted to intracellular compartments that are mostly LAMP1⁺ (blue, arrow, top panels). In cells cotransfected with BAD-LAMP-GFP and UNC93B1 (red, bottom panels), the 2 molecules are sorted together in LAMP1⁺ intracellular compartments. Pearson coefficient values are shown as R.
