Abstract
Sodium channels underlie propagated electrical signalling in most excitable cells, including neurons and the myocytes of skeletal muscle and heart. These proteins are targeted by a variety of current therapeutic drugs to combat such maladies as pain, myotonias, epilepsies and cardiac arrhythmias. Typically, these problems are associated with overactivity of sodium channels leading to hyperexcitability in the relevant tissue. More than ten distinct but closely related molecular isoforms of mammalian sodium channel are now known to be specifically expressed in different cell types and tissues. Therapeutic attenuation of sodium channel activity must be effected with great precision in both targeting and the degree of reduction in channel activity if a malfunction is to be corrected without introducing deleterious or even catastrophic side effects. Numerous natural toxins have evolved to target sodium channels, either by blocking current through the pore or by modifying channel gating. Among the well studied toxins, the peptide conotoxins from cone snail venoms show a remarkable ability to discriminate among closely related forms of sodium channel, as well as exhibiting a variety of modes of action. Here, we examine the molecular basis of action of different Na channel targeted conotoxins and explore their potential as models for the future design of more specifically targeted drugs.

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
