<i>mau-2</i>acts cell-autonomously to guide axonal migrations in<i>Caenorhabditis elegans</i>
Bibliographic record
Abstract
The gene mau-2 has been found to be required for the guidance of cellular and axonal migrations along both the anteroposterior and the dorsoventral body axes during the development of the nematode C. elegans. We show that mau-2 encodes a novel, previously uncharacterized protein that is highly conserved among animals. Maternal mau-2 gene expression is sufficient for normal development until the fourth larval stage, and a MAU-2::GFP fusion protein localizes to the cytoplasm of neurones. mau-2 is ubiquitously expressed in embryos by late gastrulation and becomes predominantly expressed in the nervous system as morphogenesis progresses. Expression of mau-2 within individual neurones rescues the guidance defects of mau-2 mutants, indicating that mau-2 functions cell-autonomously. Altering the activity of both the dorsal repellent slt-1 and mau-2 leads to the abnormal dorsal projection of the AVM axon, a phenotype that is novel and specific to the interaction of these two genes, indicating that mau-2 participates in the guidance of AVM by a slt-1-independent mechanism. Taken together, mau-2 defines a novel guidance factor that might be involved in the intracellular processing of guidance cues encountered by migrating cells and axons during development.

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.
