Abstract
A class of mitochondria-penetrating peptides (MPPs) was studied in an effort to optimize their applications in the delivery of bioactive cargo to this therapeutically important organelle. The sequence requirements for mitochondrial entry were monitored, and it was discovered that while an alternating cationic/hydrophobic residue motif is not required, the inclusion of a stretch of adjacent cationic amino acids can impede access to the organelle. In addition, a variety of N- and C-terminal cargo were tested to determine if there are limitations to the lipophilicity, charge, or polarity of compounds that can be transported to mitochondria by MPPs. The results reported demonstrate that these peptide sequences are versatile transporters that will have a range of biological applications.

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
