Abstract The cytomegalovirus (CMV) UL97 kinase inhibitor maribavir (MBV) is undergoing clinical antiviral trials. Two clinical CMV isolates serially passaged in cell culture under MBV showed >20-fold increases in MBV resistance after the development of the UL97 mutation V353A in one of the isolates and of T409M in the other. Marker transfer studies confirmed that the V353A and T409M mutations conferred ~15-fold and ~80-fold increases, respectively, in MBV resistance without significantly affecting ganciclovir susceptibility. The 3 UL97 mutations now known to confer MBV resistance are located upstream of UL97 mutations linked to ganciclovir resistance, closer to kinase domains that are associated with adenosine triphosphate binding and phosphotransfer.

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
  • Disease: An abnormal physiological state with specific symptoms and signs caused by viral infection.
  • Immune: The article focuses on the study of mutations and immune.
