we conclude that ( i ) the genes specifying gd and gb belong to different viral regulatory gene subsets , ( ii ) the gd gene is subject to both positive and negative regulation , ( iii ) both gd and ge mrnas are subject to translational controls although they may be different , and ( iv ) the absence of expression of gd in the alpha 4/bj cells reflects the expression of the alpha 4 protein in these cells .
