Fig. (3) Cellular proteins and homologous proteins found in both Ad and HSV-1 supported AAV2 RCs. The String database (http://string-db.org/) was used to reconstitute the interaction networks between identified cellular proteins or homologous proteins (as described in Fig. 1) which were found associated with both Ad and HSV-1 supported AAV2 RCs and/or the AAV2 Rep78 protein. Three functional categories, DNA replication (red), transcription (yellow), and DNA damage sensing and repair (green) are highlighted.
