Bovine Infected Cell Protein 0 (bICP0) is an immediate-early protein encoded by Bovine Herpesvirus-1 that modulates host immune response, activates transcription for all viral promoters, and causes ubiquitin-dependent degradation of proteins. Presented herein is a bICP0 protein-protein interaction (PPI) profile, consisting of 98 cellular and 15 viral proteins, generated through co-immunoprecipitation of bICP0 and its binding partners. The PPI profile was analyzed computationally to identify potential sites of interaction with bICP0 and any cellular pathways that may be influenced by bICP0. Some interactors fall in conjunction with bICP0’s known roles during infection, and others are consistent with known associations of bICP0 homologs. However, some proteins in the PPI profile are involved in apoptosis signaling and mRNA spicing—processes both significant during viral infection and novel to the known functions of bICP0 and its homologs. The interaction and co-localization of some of these proteins with bICP0 was further examined.
