The Battle for Survival: The Role of RNA Non-Canonical Tails in the Virus–Host Interaction
Terminal nucleotidyltransferases (TENTs) could generate a ‘mixed tail’ or ‘U-rich tail’ consisting of different nucleotides at the 3′ end of RNA by non-templated nucleotide addition to protect or degrade cellular messenger RNA. Recently, there has been increasing evidence that the decoration of viru...

| Summary: | Terminal nucleotidyltransferases (TENTs) could generate a ‘mixed tail’ or ‘U-rich tail’ consisting of different nucleotides at the 3′ end of RNA by non-templated nucleotide addition to protect or degrade cellular messenger RNA. Recently, there has been increasing evidence that the decoration of virus RNA terminus with a mixed tail or U-rich tail is a critical way to affect viral RNA stability in virus-infected cells. This paper first briefly introduces the cellular function of the TENT family and non-canonical tails, then comprehensively reviews their roles in virus invasion and antiviral immunity, as well as the significance of the TENT family in antiviral therapy. This review will contribute to understanding the role and mechanism of non-canonical RNA tailing in survival competition between the virus and host. |
