expression of gb was dependent on the presence of functional alpha 4 protein inasmuch as expression of gb ceased on shift up to nonpermissive temperatures , when shifted to permissive temperatures , the cell line reinitiated expression of gb after a delay commensurate with the length of incubation at the nonpermissive temperature , and the cell-resident hsv-1 gb gene was expressed at the nonpermissive temperature in cells infected with a recombinant expressing a ts+ alpha 4 protein and an hsv-2 gb .
