AstraPTM2 Preprint is Published on bioRxiv

Introducing AstraPTM2 — the next generation of residue-level PTM prediction.

After supporting PTM prediction research with Columbia University and CUNY, we’re excited to share that AstraPTM2 is now available on the Orbion platform, and the preprint is published on bioRxiv.

It’s the most comprehensive and best-performing PTM model available today.

Highlights:

• Predicts 39 distinct PTM types

• Two modes — Calibrated and Exploration

• Achieves the highest macro-F1 among PTM models

• Delivers residue-level maps in under five minutes

AstraPTM2 is already live on the Characterize platform.
