Metabolic functions of AMPK: Aspects of structure and of natural mutations in the regulatory gamma subunits
Bibliographic record
Abstract
AMP-activated protein kinase, AMPK, is widely accepted as the master regulator of energy levels within the cell. Responding quickly to changing energy demands, AMPK works to restore levels of ATP during times of cellular stress by promoting ATP producing catabolic pathways and inhibiting ATP consuming anabolic ones. As a heterotrimeric protein complex, AMPK's subunits each act in unique and crucial ways to control AMPK function and its localization within the cell. Research in the last decade has identified and begun to characterize the impact of naturally occurring mutations in the gamma regulatory subunits. Mutations in the γ2 subunit have implications for cardiac function and disease, while the R225W mutation in the γ3 subunit have implications for skeletal muscle fuel metabolism and resistance to fatigue. Research focused on structure-function aspects of AMPK regulatory subunits will lead to a better understanding of the roles of AMPK in health and disease.

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.
