Expression of glycoprotein D of herpes simplex virus

Abstract

Methods and compositions are provided for the efficient production in yeast of polypeptides which are immunologically cross-reactive with glycoprotein D of the herpes simplex virus. Synthetic DNA fragments encoding for a portion of the glycoprotein, and the naturally-occurring gene encoding for the glycoprotein and portions thereof, are expressed on plasmids in yeast. Secretion may be provided by including a secretory leader and signal processing sequence derived from the .alpha.-factor gene. Alternatively, the genes may be expressed intracellularly under the transcriptional control of a promoter derived from a gene in the yeast glycolytic pathway. E. coli strains HB101 containing plasmids pYHS109 and pYHS118 were deposited at the American Type Culture Collection on July 11, 1984, and granted accession nos. 39762 and 39763, respectively.
