Characterization of transcripts expressed from human herpesvirus 6A strain GS immediate-early region B U16-U17 open reading frames.

ABSTRACT: Several gene fragments of human herpesvirus 6 (HHV-6) have been shown to activate the human immunodeficiency virus (HIV) type 1 long terminal repeat (LTR). An open reading frame (ORF) designated B701 (Y. Geng, B. Chandran, S. F. Josephs, and C. Wood, J. Virol. 66:1564-1570, 1992), found within a 22-kb HHV-6A strain GS [HHV-6A(GS)] genomic fragment and a 3.8-kb SalI subfragment, was shown to activate the HIV LTR. B701, also known as HHV-6 U16, is located in the immediate-early B (IE-B) region of the genome. The sequence of the 3.8-kb genomic fragment of HHV-6A(GS) is nearly identical to the published sequence of HHV-6A strain U1102, with minor differences. The HHV-6A(GS) B701 ORF (U16) was used to screen an HHV-6A(GS) cDNA library, and two different but overlapping cDNAs were identified. Th
