AstraPTM Preprint on bioRxiv
Orbion’s first model, AstraPTM, is now publicly available as a preprint on bioRxiv.
What it does
Predicts post-translational modifications (PTMs) in large proteins
Uses a Transformer architecture with ESM-2 embeddings and 1,351 residue-level features
Detects even partly-characterised or previously unseen PTMs
Why it matters
AstraPTM pushes protein-scale ML forward, opening faster, more reliable routes to functional annotation and protein design.Open science
We’ve published the full “recipe” so researchers can reproduce, extend, or benchmark against our work. If you improve on AstraPTM, please cite the paper and share your results—we’d love to collaborate.
