Abstract N6-methyladenosine (m6A) is the most abundant HIV RNA modification but the interplay between the m6A reader protein YTHDF3 and HIV replication is not well understood. We found that knockout of YTHDF3 in human CD4+ T-cells increases infection supporting the role of YTHDF3 as a restriction factor. Overexpression of the YTHDF3 protein in the producer cells reduces the infectivity of the newly produced viruses. YTHDF3 proteins are incorporated into HIV particles in a nucleocapsid-dependent manner permitting the m6A reader protein to limit infection in the new target cell at the step of reverse transcription. Importantly, HIV protease cleaves the virion-incorporated full-length YTHDF3 protein, a process which is blocked by HIV protease inhibitors used to treat HIV infected patients. Mass-spectrometry confirmed the proteolytic processing of YTHDF3 in the virion. Thus, HIV protease cleaves the virion-encapsidated host m6A effector protein in addition to the viral polyproteins to ensure optimal infectivity of the mature virion.

Note
Basic Characteristics of Mutations
  • Mutation Site: The specific location in a gene or protein sequence where a change occurs.
  • Mutation Level: The level at which a mutation occurs, including the nucleotide or amino acid level.
  • Mutation Type: The nature of the mutation, such as missense mutation, nonsense mutation, synonymous mutation, etc.
  • Gene/Protein/Region: Refers to the specific region of the virus where the mutation occurs. Including viral genes, viral proteins, or a specific viral genome region. If the article does not specifically indicate the relationship between the mutation and its correspondence, the main
  • Gene/Protein/Region studied in the article is marked.
  • Genotype/Subtype: Refers to the viral genotype or subtype where the mutation occurs. If the article does not specifically indicate the relationship between the mutation and its correspondence, the main Genotype/Subtype studied in the article is marked.
  • Viral Reference: Refers to the standard virus strain used to compare and analyze viral sequences.
Functional Impact and Mechanisms
