Abstract
Previous studies have implicated a role for acidic nuclear proteins in the PHA stimulated activation of human lymphocytes. This study examines the mechanism of synthesis of these proteins. Cycloheximide inhibited their production, while Actinomycin D did not. It is suggested that synthesis proceeds by translation of dormant messenger RNA rather than of newly synthesized messenger RNA.
