Abstract
The recruitment of coactivators by nuclear hormone receptors (NRs) promotes transcription by subverting chromatin-mediated repression. Although the histone methylation enzyme CARM1 and an ATP-remodeling complex have been individually implicated in nuclear receptor-dependent transcription, neither a functional nor mechanistic linkage between these systems has been identified. In the process of purifying endogenous CARM1-interacting proteins, we identified an associated complex, nucleosomal methylation activator complex (NUMAC), which includes at least eight components of SWI/SNF, including the ATPase BRG1. In the NUMAC complex, the methylase, CARM1, acquires the ability to covalently modify nucleosomal histones, and the directed nucleosome versus free core histone methylation-specificity change is increased dramatically. Reciprocally, CARM1 stimulates the ATPase activity of BRG1, a key component in nucleosome remodeling. In vivo, CARM1 and BRG1 coassemble on an estrogen receptor (ER)-target gene to cooperatively activate ER-dependent transcription. This association of ATP-remodeling factors with HMT CARM1 defines a new component of regulation in the nuclear hormone-signaling pathway.

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
