Recombinant Ictalurid herpesvirus 1 Uncharacterized protein ORF61 (ORF61)
Description
Research on Recombinant ORF59
Key findings from studies on recombinant ORF59 include:
Absence of Data on ORF61
The search results do not describe ORF61 in IcHV-1. Notably:
Potential Explanations for the Discrepancy
-
Typographical Error: ORF61 may be a misreference to ORF59, a well-characterized glycoprotein in IcHV-1 .
-
Uncharacterized Protein: ORF61 might represent a hypothetical or unstudied open reading frame in IcHV-1, lacking experimental validation.
-
Species-Specific Homology: ORF61 homologs exist in other herpesviruses (e.g., VZV) but have not been identified in IcHV-1 .
Recommendations for Further Research
To address the absence of data on IcHV-1 ORF61:
-
Conduct genomic re-annotation to confirm the existence and structure of ORF61.
-
Perform homology modeling against known herpesvirus proteins.
-
Develop recombinant expression systems (e.g., baculovirus or E. coli) for functional studies.
