Characterization and expression of extrahepatic CYP2S1
Bibliographic record
Abstract
BACKGROUND: About one-third of the CYP enzymes identified so far, including several novel CYP enzymes such as CYP2S1, CYP2U1 and CYP2W1, belong to the CYP2 family. As with other recently discovered CYP enzymes, detailed information about the catalytic activity and function of CYP2S1 is lacking. OBJECTIVE: To review and compare the expression of CYP2S1 mRNA and protein in humans, mice and rats, and to critically examine evidence pertaining to CYP2S1 regulation and its catalytic activity. METHODS: Information about mouse and human CYP2S1 was summarized from published reports. Data about rat CYP2S1 expression was taken from recent work by the authors. RESULTS/CONCLUSIONS: CYP2S1 shares molecular characteristics of both CYP1 and CYP2 family enzymes but shows a unique tissue profile of expression. Further studies are needed to identify selective substrates and to measure CYP2S1 protein levels before the role of CYP2S1 in xenobiotic metabolism and its relevance to physiological pathways and disease states can be determined.

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.
