Abstract
Recombinant Adeno-Associated Virus (rAAV) has emerged as one of the most promising gene therapy delivery vectors. Development of these vectors took advantage of key features of the wild-type AAV virus (wtAAV), enabled by basic studies of the underlying biology and requirements for transcription, replication and packaging of the viral genome. Each step in generating and utilizing viral vectors involves numerous molecular interactions that together determine the efficiency of vector production and gene delivery. Once delivered into the cell, interactions with host proteins will determine the fate of the viral genome, and will impact the intended goal of gene delivery. Here we provide an overview of known interactions of the AAV genome with viral and cellular proteins involved in its amplification, packaging, and expression. Further appreciation of how the AAV genome interacts with host factors will enhance how this simple virus can be harnessed for an array of vector purposes that benefit human health.Keywords
