Abstract
The classic calpain system has been implicated in regulating a variety of cellular processes including cell adhesion, migration, and intracellular signaling; however, little is known regarding the function of this system in vivo. Two heterodimeric Ca(2+)-dependent cysteine proteases, mu-calpain (CAPN1) and m-calpain (CAPN2), and the endogenous inhibitor calpastatin (CAST) comprise the classic/ubiquitous calpain system in mammals. Recently, knockout of two murine classic calpain genes, Capn2 and Capn4/Capns1, revealed that components of the classic system are indispensable for preimplantation development. We identified four classic calpain catalytic subunit genes (capn1a, 1b, 2a, 2b), two regulatory subunit genes (capns1a, 1b), and calpastatin (cast) from the zebrafish. Our data suggest that the components of the classic mammalian system are both conserved and expanded in the teleost lineage. In contrast to the classic/ubiquitous mammalian system, zebrafish calpain system genes acquire unique, tissue-specific patterns of expression within the first 2 days of development.

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
