Regulation of G protein-coupled receptor endocytosis by ARF6 GTP-binding proteins
Bibliographic record
Abstract
The function of G protein-coupled receptors is regulated by a broad variety of membrane-bound and intracellular proteins. These act in concert to activate signaling pathways that will lead to the desensitization of activated receptors and, for most receptor types, their trafficking to intracellular compartments. This review focuses mainly on the endocytic pathways used by a G protein-coupled receptor and on the proteins that play an essential role in the regulation of the internalization process, most specifically the ADP-ribosylation factors. This family of proteins has been shown to be important for vesicle trafficking between different cellular membranes. The latest findings regarding the molecular mechanisms that regulate internalization of an agonist-stimulated receptor are presented here. Finally, a perspective on how ARF6 proteins might regulate the internalization process is also proposed.

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.
