Ubiquitylome study identifies increased histone 2A ubiquitylation as an evolutionarily conserved aging biomarker

Abstract excerpt

The long-lived proteome constitutes a pool of exceptionally stable proteins with limited turnover. Previous studies on ubiquitin-mediated protein degradation primarily focused on relatively short-lived proteins; how ubiquitylation modifies the long-lived proteome and its regulatory effect on adult lifespan is unclear. Here we profile the age-dependent dynamics of long-lived proteomes in Drosophila by mass...
