From T‐tubule to sarcolemma: damage‐induced dysferlin translocation in early myogenesis
Bibliographic record
Abstract
ABSTRACT The dysferlin gene is mutated in limb‐girdle muscular dystrophy type 2B, Miyoshi myopathy, and distal anterior compartment myopathy. In mature skeletal muscle, dysferlin is located predominantly at the sarcolemma, where it plays a role in membrane fusion and repair. To investigate the role of dysferlin during early muscle differentiation, its localization was studied at high resolution in a muscle cell line. This demonstrated that dysferlin is not expressed at the plasmalemma of myotubes but mostly localizes to the T‐tubule network. However, dysferlin translocated to the site of injury and toward the plasma membrane in a Ca 2+ ‐dependent fashion in response to a newly designed in vitro wounding assay. This reaction was specific to the full‐length protein, as heterologously expressed deletion mutants of distinct C2 domains of dysferlin did not show this response. These results shed light on the dynamics of muscle membrane repair and are highly indicative of a specific role of dysferlin in this process in early myogenesis.—Klinge, L., Laval, S., Keers, S., Haldane, F., Straub, V., Barresi, R., Bushby, K.

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.
