title: The 65,000-Mr DNA-binding and virion trans-inducing proteins of herpes simplex virus type 1.
abstract: The possible identity of the herpes simplex virus type 1 (HSV-1) 65K (65,000-Mr) virion protein which stimulates transcription from immediate-early genes with the HSV-1 65K DNA-binding protein was investigated. The two proteins were found to be distinct by the three separate criteria of immunological reactivity, tryptic peptide fingerprinting, and mobility in two-dimensional gels. Using HSV-1/HSV-2 intertypic recombinants and a serotype-specific antiserum, we located the gene encoding the 65K DNA-binding protein between coordinates 0.574 and 0.682 on the HSV-1 genome. The protein is posttranslationally modified by phosphorylation. In crude extracts of HSV-1-infected cells the 65K trans-inducing protein did not detectably bind to double-stranded calf thymus DNA under the conditions of our assay.
