By assaying CAT enzyme activity across a 24-h PRL induction time course, we were able to assign G1 vs. S phase PRL responses of the IRF-1 gene to different regions of the IRF-1 5'-flanking and promoter DNA .
 ( protein: CAT, None) , ( DNA: 5#$%#-flanking, None) , ( DNA: promoter DNA, None) , ( DNA: IRF-1 gene, None) , ( protein: PRL, None) , ( protein: IRF-1, None) , ( protein: IRF-1, None) , ( protein: PRL, None) , ( protein: CAT enzyme, None)
