Abstract

fetched live from OpenAlex

Le marquage protéique par fluorescence est une méthode de choix permettant d’étudier l’évolution des protéines depuis leur synthèse cellulaire jusqu’à leur dégradation, en plus de rendre possible leur localisation ainsi que la visualisation des interactions entre protéines. De cet intérêt certain ont découlé différentes techniques de marquage, dont celle présentement développée dans le groupe Keillor. Le principe de celle-ci repose sur la réaction entre deux maléimides portés par un fluorogène et une séquence peptidique cible, laquelle contient deux résidus cystéines séparés par une distance appropriée. Suite à cette double addition de thiols du peptide sur les maléimides du fluorogène, la fluorescence latente de ce dernier est régénérée, menant au marquage covalent de la protéine d’intérêt. Afin d’optimiser la spécificité et la sensibilité de cette méthode de marquage, la synthèse de nouveaux fluorogènes et l’étude de l’efficacité de quench de la fluorescence par les maléimides est présentement en cours dans les laboratoires du groupe Keillor.

Not 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.
