Abstract
Bioluminescence resonance energy transfer (BRET) allows monitoring of protein-protein interactions in real time in living cells. One candidate interacting protein is fused to a luminescent energy donor, such as Renilla luciferase, and the other to a fluorescent energy acceptor, such the green fluorescent protein (GFP), and the two are then coexpressed in the same cells. If the two proteins interact, their close proximity allows nonradiative energy transfer (BRET) between the luciferase and the GFP. BRET does not occur if the two proteins are separated by more than 100 A, making the technique ideal for monitoring protein-protein interactions in biological systems. This unit describes the use of BRET to study constitutive and agonist-promoted interactions among signaling molecules, as illustrated by the homodimerization of the CXCR4 receptor and the recruitment of beta-arrestin2 to agonist-activated G-protein-coupled receptors. This noninvasive and homogeneous assay provides a robust and sensitive proteomic platform with applications for basic science research and drug discovery.

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
