Post-Translational Modification Patterns Stay Youthful in Long-Lived Species

Mechanism: Long-lived species maintain consistent, youthful post-translational modification (PTM) patterns on their proteins, unlike short-lived species where PTM patterns diverge and become chaotic with age. Readout: Readout: This maintenance is associated with a significantly higher 'Lifespan Bar' and 'PTM Pattern Stability' score in long-lived mammals compared to short-lived ones.

Post-translational modifications accumulate differently across species. Long-lived species maintain youthful protein modification patterns despite advanced age. Acetylation, phosphorylation, and ubiquitination dynamics may diverge systematically between short and long-lived mammals.
