Δ21 IFITM3 and Y20A IFITM3 have boarder subcellular distributions.

<p>A549 cells expressing native FL IFITM3, Δ21 IFITM3, or Y20A IFITM3 were fixed, permeabilized, and labeled with anti-LAMP2 (green) and anti-IFITM2/3 (red) and DAPI (blue) antibodies. DAPI was used as nuclear counterstain. Cells were imaged by confocal microscopy. Each panel represents at least two sets of experiments with similar results.
