The Unc-119 Family of Neural Proteins is Functionally Conserved Between Humans,<i>Drosophila</i>and<i>C. Elegans</i>
Bibliographic record
Abstract
C. elegans animals mutant for the unc-119 gene exhibit movement, sensory and behavioral abnormalities. Consistent with a nervous system role, unc-119 reporter genes are expressed throughout the C. elegans nervous system. The UNC-119 protein has strong sequence similarity to the predicted protein from a human gene, HRG4/HsUNC-119, whose transcript is abundant in the retina. Using these similarities, we have identified a Drosphila homolog, DmUNC-119, which is expressed in the Drosophila nervous system. The predicted C. elegans, human and Drosophila gene products are conserved across two domains. Expression of portions of HRG4/HsUNC-119 or DmUNC-119, directed by the unc-119 promoter, can fully rescue the C. elegans unc-119 mutant phenotype. We tested the ability of portions of HRG4/HsUNC-119 to rescue, and found that its function in C. elegans requires the conserved carboxyl terminus, while the dissimilar amino terminus is dispensable. UNC-119, HRG4 and DmUNC-119 constitute members of a new class of neural genes whose common function has been maintained through metazoan evolution.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
