Nomenclature of flavivirus-specified proteins
Abstract:
Flavivirus structural proteins are designated E, C, and M, replacing the former nomenclature of V3 (envelope), V2 (core), and V1 (membrane-like) proteins, respectively. The nonstructural proteins, formerly NV1 through NV5, are designated by their apparent size in kilodaltons, prefixed by P (or GP if a glycoprotein), if they are stable unrelated end-products; the lower case p or gp is used for variants or uncharacterized products. A relationship to any structural protein is indicated by adding E, C, or M parenthetically to the designation of the appropriate nonstructural protein.
Insights
Flavivirus protein nomenclature has been updated. Structural proteins are now E, C, and M, while nonstructural proteins are designated by size (P/GP or p/gp), with structural relationships noted parenthetically.
Area of Science:
- Virology
- Molecular Biology
Background:
- The nomenclature for flavivirus proteins has historically been inconsistent.
- Previous designations for structural proteins included V1, V2, and V3.
- Nonstructural proteins were previously identified as NV1 through NV5.
Purpose of the Study:
- To clarify and standardize the nomenclature for flavivirus proteins.
- To establish a consistent naming convention for both structural and nonstructural proteins.
Main Methods:
- Review and consolidation of existing flavivirus protein designations.
- Implementation of a new systematic nomenclature based on protein function and characteristics.
Main Results:
- Structural proteins are now designated E (envelope), C (core), and M (membrane-like).
- Nonstructural proteins are designated by their molecular weight in kilodaltons (kDa), prefixed by P (or GP for glycoproteins) for stable products, and p (or gp) for variants.
- Relationships between nonstructural and structural proteins are indicated parenthetically (E, C, or M).
Conclusions:
- The revised nomenclature provides a clear and unified system for identifying flavivirus proteins.
- This standardization facilitates better communication and understanding in flavivirus research.
