Description: Expression of Human Wild-Type and P239S Mutant Palladin Constructs in HeLa Cells (A and B) When HeLa cells were transfected with the human wild-type (WT) palladin construct, filamentous bundles (A) clearly colocalized with the F-actin (B). (C and D) In contrast, expression of the mutant P239S Family X (FX) construct resulted in large palladin flower-shaped structures (arrows) in which the center, but not the petals of the flower, colocalizes with actin. (E and F) Expression of Family X constructs can also cause small cytoplasmic flecks of palladin that do not colocalize with actin. HeLa cells overexpressing the empty GFP vector displayed uniform distribution of GFP in the whole cells that did not colocalize with F-actin (unpublished data). Green, GFP-palladin; red, F-actin; blue, nucleus; yellow, colocalized palladin and F-actin. All figures are at 100× magnification.
