Abstract in brief

The study explores how age-related changes in K63-linked ubiquitination, a specific protein modification independent of proteasome degradation, affect memory in the hippocampus and amygdala, brain regions key to memory.
Researchers found that K63 polyubiquitination increases in the hippocampus with age, and reducing it improves memory in aged rats, while in the amygdala, K63 ubiquitination decreases with age, and further reductions also enhance memory.
Overall, the findings highlight that K63 polyubiquitination plays a region-specific and dynamic role in brain aging and memory decline, offering new insights into molecular mechanisms underlying age-associated cognitive loss.
