title: The herpes simplex virus type 1 immediate-early polypeptide ICP4 is required for expression of globin genes located in the viral genome.
abstract: We infected Vero cells with ICP4-deficient herpes simplex virus recombinants bearing the rabbit beta-globin and human alpha 2-globin genes under the control of their own promoters and found that globin gene expression occurred only when ICP4 was provided in trans. These results demonstrate that ICP4 is required for the activity of globin promoters located in the viral genome and support the hypothesis that these cellular promoters are functionally equivalent to HSV early regulatory regions.
