Abstract The herpes simplex virus type 1 (HSV-1) structural tegument proteins pUL36 and pUL37 are essential for secondary envelopment during the egress of viral particles. For this study, scanning alanine mutagenesis of HSV-1 pUL37, in combination with yeast two-hybrid, identified pUL37 residue D631 as a major determinant for binding of pUL36. Further analysis of the binding of this pUL37 mutant to pUL36 by coimmunoprecipitation assay confirmed the role of pUL37 D631 in mediating binding of pUL36. A trans-complementation assay using pUL37 deletion virus FRDeltaUL37 was then carried out, where pUL37 wild type or D631A were provided in trans. For pUL37 D631A, a significant reduction in virus titer was observed compared to that seen when pUL37 wild type was present. The results presented here underline the crucial role of the pUL36/pUL37 interaction in replication of HSV-1 and indicate a critical role for pUL37 D631 in mediating this interaction.

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.
