A cellular factor binds to the herpes simplex virus type 1 transactivator Vmw65 and is required for Vmw65-dependent protein-DNA complex assembly with Oct-1

Mol Cell Biol. 1990 Sep;10(9):4974-7. doi: 10.1128/mcb.10.9.4974-4977.1990.

Abstract

The herpes simplex virus transactivator Vmw65 assembles into a multicomponent protein-DNA complex along with the octamer binding protein Oct-1. Using affinity chromatography on columns conjugated with purified Vmw65 fusion protein expressed in Escherichia coli, we demonstrate that a cellular factor, distinct from Oct-1, binds to Vmw65 in the absence of target DNA and is necessary for Vmw65-mediated complex assembly with Oct-1.
