Abstract
Color vision is supported by retinal cone photoreceptors that, in most mammals, express two photopigments sensitive to short (S-opsin) or middle (M-opsin) wavelengths. Expression of the Opn1sw and Opn1mw genes, encoding S-opsin and M-opsin, respectively, is under the control of nuclear receptors, including thyroid hormone receptor beta2 (TRbeta2), retinoid X receptor gamma (RXRgamma), and RORbeta, a member of the retinoic acid receptor-related orphan receptor (ROR) family. We now demonstrate that RORalpha, another member of the ROR family, regulates Opn1sw, Opn1mw, as well as Arr3 (cone arrestin) in the mouse retina. RORalpha expression is detected in cones by postnatal day 3 and maintained through adulthood. The retinas of staggerer mice, carrying a null mutation of RORalpha, show significant down-regulation of Opn1sw, Opn1mw, and Arr3. RORalpha acts in synergy with cone-rod homeobox transcription factor (Crx), to activate the Opn1sw promoter in vitro. Chromatin immunoprecipitation assays reveal that RORalpha directly binds to the Opn1sw promoter, Opn1mw locus control region, and the Arr3 promoter in vivo. Our data suggest that RORalpha plays a crucial role in cone development by directly regulating multiple cone genes.

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 it
