These regions were identified as promoters by excising them from the VV ge nome, abutting them to the bacterial chloramphenicol acetyl transferase gene, and demonstrating their ability to drive expression of the reporter gene in tr ansient-expression assays in an orientation-specific manner.

In marked contrast to previous 5' dele tion analyses which have identified VV late promoters as 20- to 30-base-pair c ap-proximal sequences, 5' deletions to define the upstream boundary of the ORF D13 promoter identified two positive regulatory regions, the first between -2 35 and -170 and the second between -123 and -106.

The first region, loc ated within 50 nucleotides (position -50) 5' to the transcription initiation ( cap) site, contains a G+C-rich consensus-binding site (GC box) for the transcr iption factor Sp1 and a TATA box. Unambiguous stimulatory activity of the seco nd region, between positions -358 and -127, was observed only in the absence o f the GC box. DNase I protection experiments (footprinting) with crude nuclear extracts from uninfected cells revealed multiple DNA-protein interactions at the control region. Proximal to the initiation site, both the GC box and the c ap site were protected; however, protection of the TATA box was not observed. In the distal region, four protein-binding sites, designated I through IV, wer e located between positions -250 and -120. Three of the four mapped in protein -coding sequences of the adjacent E1a gene. Sites I and II were 5' to position -218 whereas sites III and IV were 3' to position -218. This finding was cons istent with results of the transcriptional analysis indicating that subsets of the distal region were sufficient for stimulation of transcription in vitro i n the absence of the GC box.

Subgroup D viruses are closely relate d to the subgroup B viruses but have an extended host range that includes the ability to penetrate certain mammalian cells. There are 27 amino acid differen ces shared between the subgroup D sequence and three subgroup B sequences. At 16 of these sites, the subgroup D sequence is identical to the sequence of one or more of the other subgroup viruses (A, C, and E). The remaining 11 sites a re specific to subgroup D and show some clustering in the two large variable r egions that are thought to be major determinants of host range. Biological ana lysis of recombinant viruses containing a dominant selectable marker confirmed the role of the gp85-coding domain in determining the host range of the subgr oup D virus in the infection of mammalian cells. We also compared the sequence of the gp85-coding domain from two subgroup A viruses, Rous-associated virus type 1 and a subgroup A virus of the Schmidt-Ruppin strain of Rous sarcoma vir us. The comparison revealed 24 nonconservative amino acid changes, of which 6 result in changes in potential glycosylation sites. The positions of 10 amino acid differences are coincident with the positions of 10 differences found bet ween two subgroup B virus env gene sequences.
