Abstract
Notch-mediated induction of Nodal at the vertebrate node is a critical step in initiating left-right (LR) asymmetry. In mice and zebrafish we show that Baf60c, a subunit of the Swi/Snf-like BAF chromatin remodeling complex, is essential for establishment of LR asymmetry. Baf60c knockdown mouse embryos fail to activate Nodal at the node and also have abnormal node morphology with mixing of crown and pit cells. In cell culture, Baf60c is required for Notch-dependent transcriptional activation and functions to stabilize interactions between activated Notch and its DNA-binding partner, RBP-J. Brg1 is also required for these processes, suggesting that BAF complexes are key components of nuclear Notch signaling. We propose a critical role for Baf60c in Notch-dependent transcription and LR asymmetry.

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
