In the article "A family of proteins structurally and functionally related to the E6-AP ubiquitin-protein ligase" by Jon M. Huibregtse, Martin Scheffner, Sylvie Beaudenon, and Peter M. Howley, published in *Proc. Natl. Acad. Sci. USA* (92, 2563–2567) on March 28, 1995, the authors noted an error in the preparation of Fig. 1B. During the alignment of protein sequences, the first 10–13 amino acids of five sequences were inadvertently interchanged. Specifically, the first 13 amino acids of the rat p100 sequence were found in the NEDD-4 sequence, and the corresponding region of NEDD-4 was found in YKL162, and so on. This error does not affect the interpretation of the results or the conclusions of the paper. The corrected Fig. 1B is provided. In the article "Rapid gene-specific repair of cisplatin lesions at the human *DUG/DHFR* locus comprising the divergent upstream gene and dihydrofolate reductase gene during early G1 phase of the cell cycle assayed by using the exonucleolytic activity of T4 DNA polymerase" by Nicholas J. Rampino and Vilhelm Bohr, published in *Proc. Natl. Acad. Sci. USA* (91, 10977–10981) on November 8, 1994, the authors noted a discrepancy between the percentage of hybridization measured in Fig. 3 and Fig. 4. They attributed this discrepancy to an age-associated decline in the potency of their cisplatin solution, as the data in Fig. 3 were obtained later than those in Fig. 4. The authors did not measure the cisplatin concentration using other techniques, suggesting that the assay may be less sensitive to cisplatin than reported. However, they emphasized that the main observations and implications regarding gene-specific and preferential DNA repair remain unaffected by this modification.In the article "A family of proteins structurally and functionally related to the E6-AP ubiquitin-protein ligase" by Jon M.
