Influenza C virus RNA 7 codes for a nonstructural protein
Journal of Virology
|October 1, 1985
Summary
Researchers sequenced RNA segment 7 from influenza C virus, identifying a gene encoding a 28,500-molecular-weight protein. This protein is likely a nonstructural protein, contributing to viral replication.
Area of Science:
- Virology
- Molecular Biology
- Genetics
Background:
- Influenza C virus is an important human pathogen.
- Understanding influenza virus gene function is crucial for developing antiviral strategies.
Purpose of the Study:
- To determine the complete nucleotide sequence of RNA segment 7 of influenza C/California/78 virus.
- To identify the protein encoded by RNA segment 7 and characterize its function.
Main Methods:
- Cloning of cDNA derived from viral RNA.
- Nucleotide sequencing of the cloned cDNA.
- Hybrid arrest translation experiments using cloned cDNA fragments and infected cell RNA.
- Molecular weight determination of the encoded protein.
Main Results:
- The complete nucleotide sequence of RNA segment 7 was determined.
- RNA segment 7 is 934 nucleotides long and contains an open reading frame for a 286-amino acid protein.
- Hybrid arrest translation identified a 28,500-molecular-weight protein coded by RNA 7.
- This protein was identified as a nonstructural protein.
Conclusions:
- Influenza C virus RNA segment 7 encodes a nonstructural protein of 28,500 molecular weight.
- This finding contributes to the understanding of influenza C virus genome organization and protein function.
