CELL BIOLOGY Nailing Down the Effects of Arginylation

Arginylation is a posttranslational modification critical for embryonic development, but the protein targets and molecular effects of arginylation are largely unknown. Karakozova et al. show the regulation of a single target protein by arginylation with effects on the molecular and cellular level. β-actin, an abundant, essential intracellular protein, is arginylated in vivo, and this modification regulates actin polymerization, cell motility, and lamella formation in motile cells.
