using mutant c-myc proteins and proteins that fuse portions of c-myc to chicken muscle pyruvate kinase , we found that residues 320 to 328 ( paakrvkld ; peptide m1 ) induced complete nuclear localization , and their removal from c-myc resulted in mutant proteins that distributed in both the nucleus and cytoplasm but retained rat embryo cell cotransforming activity .
