Plakins in striated muscle
Bibliographic record
Abstract
Striated muscle cells contain numerous architectural proteins that contribute to the function of muscle as generators of mechanical force. Among these proteins are crosslinkers belonging to the plakin family, namely plectin, microtubule-actin crosslinking factor (ACF7/MACF1), bullous pemphigoid antigen 1 (Bpag1/dystonin), and desmoplakin. These plakin family members, in particular plectin and Bpag1/dystonin, exist as several isoforms. The domain organization of these plakin variants dictates their subcellular location and the proteins with which they interact. Several studies suggest that plakins exert unique functions within various compartments of the muscle cell including the sarcolemma, the sarcomere, both neuromuscular and myotendinous junctions in skeletal muscle, and the intercalated discs in cardiac muscle. Plakins may also regulate the cellular placement and function of specific organelles, notably the nucleus, mitochondria, Golgi apparatus, and sarcoplasmic reticulum. Here we review and summarize our current knowledge of the function of plakins in striated muscle cells.

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.
