Figure 6. The p14 endodomain is a soluble nucleocytoplasmic peptide.

Figure 6

(A) Cells were co-transfected with HA-tagged p14 and FLAG-tagged p14 endodomain, fixed and permeabilized at 8 h post-transfection, and stained using rabbit anti-HA and mouse anti-FLAG antibodies and appropriate fluorescently tagged secondary antibodies. The HA-tagged p14 (left panel) exhibited punctate, reticular staining in the cytoplasm while the FLAG-tagged p14 endodomain (right panel) was broadly distributed throughout the cytosol and nucleus. Scale bar = 20 µm. (B) Cells were co-transfected with the indicated expression plasmids (p14, full-length p14; V, empty vector; FE, FLAG-tagged p14 endodomain), and cell lysates were fractionated into the cytosolic “C” and membrane “M” fractions before being processed for Western blotting using anti-p14 or anti-FLAG antibodies (indicated on the left).
