New Method Flags Protein Acetylation
Acetylation of lysine residues in proteins plays a key role in modulating biological activities. For example, acetylation of histones, the protein spools for DNA in cells, helps regulate gene expression. Acetylation is typically detected by radiolabeling techniques, but researchers at Rockefeller University are now reporting a faster, safer method for identifying proteins that undergo this posttranslational modification (J. Am. Chem. Soc., DOI: 10.1021/ja908871t). Yu-Ying Yang, Janice M. Ascano, and Howard C. . . .
