Abstract

fetched live from OpenAlex

> La voie de signalisation ERK (extracellular signal-regulated kinase) consiste en une squence de protines kinases, RAF/ MEK(MAP/ERK kinase)/ERK, impliques dans l'activation des kinases ERK1 et ERK2 [1, 2]. Chez les mammifres, chaque niveau de cette voie implique plus d'une enzyme. Ainsi, trois protines RAS codes par les gnes paralogues 1 Kras, Hras et Nras peuvent lier et activer les trois protines kinases RAF codes par les gnes Araf, Braf et Raf1. Les protines RAF, une fois actives, peuvent phosphoryler et activer les kinases MEK1 et MEK2, codes par les gnes Mek1 et Mek2. MEK1 et MEK2 sont responsables de la phosphorylation des protines ERK1 et ERK2, codes par les gnes Erk1 et Erk2. MEK1 et MEK2 sont les seules kinases connues capables d'activer ERK1 et ERK2, et elles sont considres, ce titre, comme des cibles thrapeutiques prometteuses, puisque la suractivation des kinases ERK est frquemment observe dans diverses maladies, incluant les cancers et les maladies auto-immunes. La prsence de plusieurs paralogues aux diffrents niveaux de cette voie de signalisation reflte d'ailleurs la complexit du contrle de son activation dans les diffrents processus cellulaires o elle est implique chez les mammifres. La voie ERK est active par plusieurs types de rcepteurs, dont les rcepteurs de l'antigne des lymphocytes B (B-cell receptor, BCR) et des lymphocytes T

Full frame distilled prediction

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.
