Abstract
G-protein coupled receptors (GPCRs) are the largest single family of signaling molecules in mammals and represent approximately 2-3% of all genes in the human genome. Estimates of the total number of GPCR genes in the human genome range from about 750 to 1000. GPCRs mediate signaling by a wide variety of ligands including amino acids, ions, biogenic amines, peptides, glycoproteins, light, pheromones, and odorants. There are presently only a handful of GPCRs whose structures have been elucidated. Of these, the mGluR1 subtype of metabotropic glutamate receptor (mGluR) and rhodopsin are the most widely used in modeling GPCRs. In the case of mGluR1, the three-dimensional structure of the extracellular ligand binding domain of the molecule has been solved, while the crystallographic data for rhodopsin encompasses the whole protein in the ground state with bound 11-cis-retinal. In this review, we discuss the use of homology modeling to investigate the structures and functions of GPCRs. We illustrate the use of homology modeling with a particular emphasis on ligand and drug binding sites in the Family C subfamily of GPCRs.

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 it
