Abstract
characterization demonstrated that, although 39F7 does not compete with FGF21, it is specific for β-Klotho/FGFR1c activation. Furthermore, the agonistic activity of 39F7 required the full IgG molecule to be bivalent, suggesting that 39F7 functions by promoting receptor/co-receptor dimerization. Supported by negative stain EM analysis of full-length β-Klotho, we propose a molecular model wherein the agonistic antibody 39F7 acts in a β-Klotho- and FGFR1c-dependent manner, mimicking FGF21 activity. More importantly, 39F7 offers promising therapeutic potential in the axis of FGF21 signaling as an antibody therapy alternative to FGF21 analogs for treatment of metabolic diseases.

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
