Fig. 4. Subcellular distribution of 14-3-3 after biochemical cell fractionation. HaCaT cells were fractionated into a cytosolic (C) and nuclear extract (N). Equal amounts of total protein from both extracts were analysed by western blotting. (A) Blot stained with specific 14-3-3
antibodies or (B) specific 14-3-3
antibodies. (C) Control probed with antibodies against known nuclear (p53), cytoplasmic (RasGAP, PKC
) and cytoskeletal (actin,
-tubulin) proteins.
