Abstract
The NIMA kinases are one of several families of kinases that participate in driving the eukaryotic cell cycle. NIMA-related kinases have been implicated in G2/M progression, chromatin condensation and regulation of the centrosome cycle. Here we report the identification of a new member of this family, FA2, from Chlamydomonas reinhardtii. FA2 was originally discovered in a genetic screen for deflagellation-defective mutants. We have previously shown that FA2 is essential for basal-body/centriole-associated microtubule severing. We now report that the FA2 NIMA-related kinase also plays a role in cell cycle progression in Chlamydomonas. This is the first indication that members of the NIMA family might exert their effects through the regulation of microtubule severing.

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
