Transcriptional analysis of the adeno-associated virus integration site.

ABSTRACT: The nonpathogenic human adeno-associated virus type 2 (AAV-2) has adopted a unique mechanism to site-specifically integrate its genome into the human MBS85 gene, which is embedded in AAVS1 on chromosome 19. The fact that AAV has evolved to integrate into this ubiquitously transcribed region and that the chromosomal motifs required for integration are located a few nucleotides upstream of the translation initiation start codon of MBS85 suggests that the transcriptional activity of MBS85 might influence site-specific integration and thus might be involved in the evolution of this mechanism. In order to begin addressing this question, we initiated the characterization of the human MBS85 promoter region and compared its transcriptional activity to that of the AAV-2 p5 promoter. Our results cle
