Biochemistry. In the article “Molecular cloning and characterization of a cellular phosphoprotein that interacts with a conserved C-terminal domain of adenovirus E1A involved in negative modulation of oncogenic transformation” by Ute Schaeper, Janice M. Boyd, Sulekha Verma, Erik Uhlmann, T. Subramanian, and G. Chinnadurai, which appeared in number 23, November 7, 1995 of Proc. Natl. Acad. Sci. USA (92, 10467–10471), we reported the sequences for human CtBP. Reexamination of the cDNA sequences revealed certain errors. These errors have been corrected in the GenBank database (accession no. U37408).
