RESUMO
The BglII N fragment of herpes simplex virus type 2 (HSV-2) DNA (approximately 0.58 to 0.63 map unit) was examined for encoded products. Using plasmid pGZ59, which consists of BglII-N cloned in pAT153, in conjunction with hybrid arrested translation, mRNA selection, and in vitro protein synthesis, we found that the major translated product of this region has an approximate molecular weight of 37,800. By further mapping, coding sequences for this polypeptide were located within the region of BglII-N representing approximately 0.58 to 0.61 genome map unit. To demonstrate immunological specificity, we used staphylococcal A protein immunoprecipitation with rabbit anti-HSV-1 or HSV-2 sera and antigens from HSV-1 or HSV-2 total mRNA translated in vitro and BglII-N-selected mRNA. The results show that the 37,800-dalton polypeptide has HSV-2 immunological specificity, as it is precipitated with anti-HSV-2 sera but not with anti-HSV-1 or control sera.
