Adeno-associated viruses (AAV) contain minimal viral proteins necessary for their replication. During virus assembly, AAV acquire, inherently and submissively, various cellular proteins. Our previous studies identified the association of AAV vectors with the DNA binding protein nucleophosmin (NPM1). Nucleophosmin has been reported to enhance AAV infection by mobilizing AAV capsids into and out of the nucleolus, indicating the importance of NPM1 in the AAV life cycle; however the role of NPM1 in AAV production remains unknown. In this study, we systematically investigated NPM1 function on AAV production using NPM1 knockdown cells and revealing for the first time the presence of G-quadruplex DNA sequences (GQRS) in the AAV genome, the synergistic NPM1-GQRS function in AAV production and the significant enhancement of NPM1 gene knockdown on AAV vector production. Understanding the role of cellular proteins in the AAV life cycle will greatly facilitate high titre production of AAV vectors for clinical use.
