CECR2, a protein involved in neurulation, forms a novel chromatin remodeling complex with SNF2L
Bibliographic record
Abstract
Chromatin remodeling complexes play critical roles in development. Here we describe a transcription factor, CECR2, which is involved in neurulation and chromatin remodeling. CECR2 shows complex alternative splicing, but all variants contain DDT and bromodomain motifs. A mutant mouse line was generated from an embryonic stem cell line containing a genetrap within Cecr2. Reporter gene expression demonstrated Cecr2 expression to be predominantly neural in the embryo. Mice homozygous for the Cecr2 genetrap-induced mutation show a high penetrance of the neural tube defect exencephaly, the human equivalent of anencephaly, in a strain-dependent fashion. Biochemical isolation of CECR2 revealed the presence of this protein as a component of a novel heterodimeric complex termed CECR2-containing remodeling factor (CERF). CERF comprises CECR2 and the ATP-dependent chromatin remodeler SNF2L, a mammalian ISWI ortholog expressed predominantly in the central nervous system. CERF is capable of remodeling chromatin in vitro and displays an ATP hydrolyzing activity that is stimulated by nucleosomes. Together, these data identify a novel chromatin remodeling complex with a critical role in neurulation.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
