DIM-1, a Novel Immunoglobulin Superfamily Protein in <i>Caenorhabditis elegans</i>, Is Necessary for Maintaining Bodywall Muscle Integrity
Bibliographic record
Abstract
The UNC-112 protein is required during initial muscle assembly in C. elegans to form dense bodies and M-lines. Loss of this protein results in arrest at the twofold stage of embryogenesis. In contrast, a missense mutation in unc-112 results in viable animals that have disorganized bodywall muscle and are paralyzed as adults. Loss or reduction of dim-1 gene function can suppress the severe muscle disruption and paralysis exhibited by these mutant hermaphrodites. The overall muscle structure in hermaphrodites lacking a functional dim-1 gene is slightly disorganized, and the myofilament lattice is not as strongly anchored to the muscle cell membrane as it is in wild-type muscle. The dim-1 gene encodes two polypeptides that contain three Ig-like repeats. The short DIM-1 protein isoform consists entirely of three Ig repeats and is sufficient for wild-type bodywall muscle structure and stability. DIM-1(S) localizes to the region of the muscle cell membrane around and between the dense bodies, which are the structures that anchor the actin filaments and may play a role in stabilizing the thin rather than the thick filament components of the sarcomere.

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.
