Evolution and Differentiation of the Prion Protein Gene (PRNP) among Species
Bibliographic record
Abstract
A total of 937 prion protein gene (PRNP) sequences belonging to 83 species in 56 genera of 26 families were analyzed in order to investigate its evolution and differentiation among species. The length of PRNP coding sequence for all species analyzed varied from 567 to 825 bp, which was mainly because of insertion or deletion in the repeat region within and among the species. TGA and TAG are the main stop codons in the PRNP gene. Bos taurus had the smallest variation in terms of average number of nucleotide differences (0.811), nucleotide diversity (0.0011), and nonsynonymous nucleotide diversity (0.0002) among all the ruminants. The reconstructed phylogenetic tree of PRNP of families and species was basically consistent with the taxonomy of National Center for Biotechnology Information except for Felidae (Felis catus), which was initially clustered with Moschidae rather than Mustelidae or Canidae.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
