Ubiquitin Rides Again
A new Nature paper introduces a high‑throughput assay that reveals ubiquitination of non‑protein substrates, most notably glycogen. The study shows that ubiquitinated glycogen is routed to lysosomes for degradation, a pathway that intensifies during fasting and is disrupted in glycogen storage diseases. The authors report a surprisingly abundant and diverse set of ubiquitinated non‑protein molecules, suggesting that ubiquitin signaling extends far beyond protein turnover. These findings compel a reassessment of cellular metabolism models and open new therapeutic avenues.
