Nucleolin directly mediates Epstein-Barr virus immune evasion through binding to G-quadruplexes of EBNA1 mRNA
Abstract
Cells infected with Epstein-Barr virus (EBV) express the virus-encoded EBNA1, which is essential for viral genome maintenance but also highly antigenic. Here the authors implicate nucleolin as a host factor that mediates the repression of EBNA1-derived antigenic peptides through binding of the G4-quadruplex structure present within the EBNA1 mRNA.
