Abstract

fetched live from OpenAlex

Type I interleukin-1 receptor is the prototype for a family of proteins, which play a central role in early responses to injury and infection. The similarity of function across the family is reflected in similarity in signaling: all members tested couple to activation of NFkappaB and stress kinases. The coupling to these pathways is mediated by a 200-residue intracellular domain (the Toll/interleukin-1 receptor domain), in which sequence conservation is primarily confined to three short motifs (boxes 1, 2, and 3) located at amino acid residue positions 10 (box 1), 60 (box 2), and 170 (box 3). We have analyzed the contribution of these motifs to function by alanine scanning mutagenesis of the human interleukin-1 receptor type I. Mutant receptors were tested for expression, ligand binding, activation of receptor-associated kinase(s), NFkappaB, stress kinases, and transcription. Mutations in all three motifs led to low cell surface expression. Mutants in box 3 were, however, wild type for signaling, whereas mutants in boxes 1 and 2 were defective. We conclude that the conserved motifs box 1 and box 2 mediate the coupling of molecules in the family to inflammation signaling pathways.

Teacher imitation

Not 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.
