Expression atlas of the multivalent epigenetic regulator Brpf1 and its requirement for survival of mouse embryos
Bibliographic record
Abstract
Bromodomain- and PHD finger-containing protein 1 (BRPF1) is a unique epigenetic regulator that contains multiple structural domains for recognizing different chromatin modifications. In addition, it possesses sequence motifs for forming multiple complexes with three different histone acetyltransferases, MOZ, MORF, and HBO1. Within these complexes, BRPF1 serves as a scaffold for bridging subunit interaction, stimulating acetyltransferase activity, governing substrate specificity and stimulating gene expression. To investigate how these molecular interactions are extrapolated to biological functions of BRPF1, we utilized a mouse strain containing a knock-in reporter and analyzed the spatiotemporal expression from embryos to adults. The analysis revealed dynamic expression in the extraembryonic, embryonic, and fetal tissues, suggesting important roles of Brpf1 in prenatal development. In support of this, inactivation of the mouse Brpf1 gene causes lethality around embryonic day 9.5. After birth, high expression is present in the testis and specific regions of the brain. The 4-dimensional expression atlas of mouse Brpf1 should serve as a valuable guide for analyzing its interaction with Moz, Morf, and Hbo1 in vivo, as well as for investigating whether Brpf1 functions independently of these three enzymatic epigenetic regulators.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
