Virus Mutation EBV Mutation K207A


Basic Characteristics of Mutations
Mutation Site K207A
Mutation Site Sentence The BZLF1 mutant proteins all gave similar levels of protein expression (measured by the incorporation of [35S]Met) when translated in vitro in reticulocyte lysate (Fig. ​2A), and all apart from K207A/L214A gave a measureable shift in the EMSA (Fig. ​2B).

Title Interaction of Epstein-Barr virus BZLF1 C-terminal tail structure and core zipper is required for DNA replication but not for promoter transactivation

Abstract The Epstein-Barr virus (EBV) protein BZLF1 contains a bZIP DNA binding domain in which C-terminal tail residues fold back against a zipper region that forms a coiled coil and mediates dimerization. Point mutagenesis in the zipper region reveals the importance of individual residues within the (208)SSENDRLR(215) sequence that is conserved in C/EBP for transactivation and EBV DNA replication. The restoration of BZLF1 DNA replication activity by the complementation of two deleterious mutations (S208E and D236K) indicates that the interaction of the C-terminal tail and the core zipper is required for DNA replication, identifying a functional role for this structural feature unique to BZLF1.

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.
