Abstract Influenza A viruses of subtype H9N2 are wide spread among poultry and other mammalian species. Crossing the species barrier from poultry to human occurred in recent years creating a pandemic of H9N2 virus. It is known that the pathogenicity of H9N2 is lower than H5N1. Nonetheless, it is important to establish the molecular functions of H9N2 viral proteins. We studied mutations in the polymerase protein PB2 of H9N2 from different strains and compared it with the highly pathogenic H5N1. The mutation M294T was found to be important in the N-myristoylation domain of Ck/UP/2573/India/04(H9N2) isolate. Prediction of secondary structures and PROSITE motif assignments were performed for PB2 to gain functional insight. Subsequently, the effect of mutations in secondary structures among strains is discussed.

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
