Direct combinatorial interaction between a herpes simplex virus regulatory protein and a cellular octamer-binding factor mediates specific induction of virus immediate-early gene expression.

Abstract: We provide evidence for a novel mechanism of transcriptional regulation in which the immediate-early (IE) transactivating protein of herpes simplex virus, Vmw65, is assembled into a specific DNA-binding complex together with a cellular octamer-binding factor (TRF). The assembly of Vmw65/TRF complex requires not only the core TRF recognition site, but also flanking sequences which are dispensable for TRF binding alone. We show from functional analyses that TRF binding by a motif is required but not sufficient… Show more

“…A cis-acting sequence, TAATGARAT (R = purine), is found at least once in all of these immediate-early gene promoters and is required for Vmw65 transactivation (26). Vmw65, however, does not bind DNA directly and has recently been shown to require complex formation with an octamer-binding protein very similar to, if not identical with, OTF-1 in order to exert its activity (11,19,30,31,36,49). The octamer-binding protein binds the TAATGARAT sequence but cannot transactivate these promoters without the presence of Vmw65.…”

“…Indeed, the ubiquitous complex x/xЈ and the brain-specific complexes y and z, but not the liver complex u, were totally displaced by the Oct oligonucleotide (Fig. 2, A and B, lanes 4), containing the Oct-1-binding site TAATGARAT of a herpes simplex virus immediate-early gene promoter (22,32). The CRH II oligonucleotide, matching with the preferential affinity consensus sequence CATnTAAT for the class III POU proteins (23), was also able to abolish formation of complexes x, y, and z with brain extracts (Fig.…”

“…This region possesses a TAAT-GARATTC consensus motif which is the binding site for the VmW65-multiprotein complex (O'Hare et al, 1988), as well as a TATA box and CCCGCCC motif. Located further upstream is the Oris which contains the 9 bp consensus sequence CGTTCGCAC at position -1612 that has been identified in both HSV-1 and VZV origins of replication.…”

“…This is the binding site for the viral tegument protein VmW65 (also known as a-TIF and VP16) (Campbell et al, 1984;Preston et al, 1984). VmW65 does not attach directly to DNA (Marsden et al, 1987), but binds one or more host cellular factors (including Oct-l) to form a multiprotein complex IEC which interacts with TAATGARATTC (O'Hare et al, 1988;Preston et al, 1988). After interaction of the multiprotein complex with the cis-acting sequences upstream of the mRNA start site, the strongly acidic Cterminal 80 amino acids of VmW65 bind the transcription complex and enhance transcription Sadowski et al, 1988;Cousens et al, 1989).…”
