CELL BIOLOGY. For the article “Element-specific localization of Drosophila retrotransposon Gag proteins occurs in both nucleus and cytoplasm,” by S. Rashkova, S. E. Karam, and M.-L. Pardue, which appeared in number 6, March 19, 2002, of Proc. Natl. Acad. Sci. USA (99, 3621–3626; First Published March 12, 2002; 10.1073/pnas.032071999), the authors note that the positions of the molecular mass markers in Fig. 3 were incorrect. The corrected figure and its legend appear below.
Figure 3.
Fusion proteins are stable and of the expected size. Total protein from transfected SL2 cells were separated by SDS/PAGE and analyzed by immunoblotting with anti-GFP antiserum to detect all GFP-tagged proteins. Expressed proteins were: 1, HeT-A Gag; 2, TART Gag; 3, jockey Gag; 4, Doc Gag; 5, I factor Gag; 6, GFP; 7, nontransfected cells. Molecular mass (kDa) is shown on the left.
