Abstract

fetched live from OpenAlex

West Nile virus (WNV) is a mosquito-borne disease that emerged in North America. In 2002 it caused the largest arboviral meningoencephalitis outbreak ever recorded in the US and Canada. The key enzyme responsible for the replication of the virus is the RNA-dependent RNA polymerase (RdRp) enzyme represented by nonstructural protein NS5 in WNV. To understand the structural basis and enzymatic activity of WNV RdRp as well as potential drug susceptibility, we have built a homology model of WNV NS5 RdRp based on a combination of motif search, fold recognition and sequence alignments orchestrated by 3D-jury system. We have located conserved sequence motifs shared by all RdRps and described the potential functional role of these motifs and specific residues in the polymerization and in the recognition of potential inhibitors. Virtual docking of several substrates and inhibitors in our WNV RdRp model shows that a non-nucleoside inhibitor such as 2'-methyl-ribofuranosyl-guanosine triphosphate has a higher binding energy indicated by a low free energy obtained upon binding. These results provide a preliminary basis for the development of anti-WNV agents based on RNA dependant RNA polymerase inhibition.

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
