RESUMO
We describe a 2560 base pair herpes simplex virus type 1 (HSV-1) DNA sequence containing the entire immediate-early mRNA-5 (IEmRNA-5) gene. The 3' and 5' termini of IEmRNA-5 were mapped within this DNA sequence by single-strand specific endonuclease protection experiments. The IEmRNA-5 gene contains DNA sequences from both the unique (Us) and reiterated (TRs/IRs) regions of the HSV-1 DNA short component and is interrupted by a single intron mapping in TRs/IRs. A search of the transcribed DNA sequence revealed no initiator codon within TRs/IRs. The first ATG was located 6 bases into Us sequences and this reading frame (316 codons) was also observed in the 3' transcribed region. The oligonucleotide sequences adjacent to the IEmRNA-5 termini are discussed in relation to those of the HSV-1 thymidine kinase gene and other genes transcribed by RNA polymerase II.
