the use of various deleted forms of e1a protein synthesized in e. coli shows that a first exon-encoded domain of e1a , residing between amino acid residues 23 and 120 , is sufficient for the posttranslational modification and nuclear localization of e1a and also for the trans-activation of the e3 promoter by e1a in xenopus oocytes .
