==Overview==
==Overview==
On infection, the herpes simplex virus (HSV) virion protein VP16 (Vmw65;, alphaTIF) forms a transcriptional regulatory complex-the VP16-induced, complex-with two cellular proteins, HCF and Oct-1, on VP16-responsive, cis-regulatory elements in HSV immediate-early promoters called TAATGARAT., Comparison of different HSV VP16 sequences reveals a conserved core region, that is sufficient for VP16-induced complex formation. The crystal, structure of the VP16 core has been determined at 2.1 A resolution. The, results reveal a novel, seat-like protein structure. Together with the, activity of mutant VP16 proteins, the structure of free VP16 suggests that, it contains (1) a disordered carboxy-terminal region that associates with, HCF, Oct-1, and DNA in the VP16-induced complex, and (2) a structured, region involved in virion assembly and possessing a novel DNA-binding, surface that differentiates among TAATGARAT VP16-response elements.
