Abstract

Background: N6-methyladenosine (m6A) modification is the most prevalent internal modification of eukaryotic mRNA modulating gene expression. m6A modification is a dynamic reversible process regulated by three protein groups: methyltransferases (writers), demethylases (erasers), and m6A-binding proteins (readers). m6A modification is involved in all phases of RNA metabolism, including RNA folding, stability, splicing, nuclear exporting, translational modulation and degradation.

Main body: In recent years, numerous studies have reported that abnormal m6A modification causes aberrant expression of important viral genes. Herein, we review the role of m6A in viral lifecycle and its contribution to the pathogenesis of human diseases. Particularly, we focus on the viruses associated with human diseases such as HIV-1, IAV, HBV, HCV, EBV and many others.

Conclusions: A better understanding of m6A-virus relationship would provide new insights into the viral replication process and pathogenesis of human diseases caused by viruses. In addition, exploration of the role of m6A in disease-causing viruses will reveal novel approaches for the treatment of such diseases.

Keywords: Demethylases; Methyltransferases; N6-methyladenosine (m6A); Viral diseases; m6A-binding proteins.

A schematic model that illustrates the roles and regulation of m6A modification. m6A modification is regulated by “writers” “erasers” and “readers”. Writers and erasers are mainly located in the nucleus, where they modulate mRNAs splicing and nuclear export. YTHDC1 and HNRP2AB1 as nuclear readers also play a vital role in nuclear export. In the cytoplasm, YTHDF2 promotes degradation of mRNA; whereas YTHDF1/3, YTHDC2 and eIF3 participate in translation
