As obligate parasites, viruses have evolved strategies to hijack cellular pathways and persist in their host, sometimes without causing overt diseases. As such, they represent unique tools to decipher cellular functions and their consequences on host physiology. Here, we exploited the natural property of a virus-encoded protein known to act as a decoy substrate for protein kinase C (PKC), a pathway thought to play key roles in learning and memory processes. When selectively expressed in the hippocampal dentate gyrus of mice, this protein caused behavioral abnormalities, notably increased anxiety and impaired memory, mostly by interfering with PKC-dependent phosphorylation. Our findings provide further insight into the role of the PKC pathway in controlling cognitive functions.
