Protein degradation rate helps explain why humans develop more slowly than mice

Phys.org reports that researchers comparing about four thousand proteins shared between humans and mice found that proteins tend to break down more slowly in humans. This slower degradation contrasts with the faster turnover observed in mice, a pattern that aligns with the generally quicker development of the rodent species. The teams suggest that the reduced protein turnover may help explain why human development proceeds at a more gradual pace than in mice.
