Human embryonic stem cells (hESCs) are shown to have high 26S/30S proteasome activity owing to increased expression of the 19S proteasome subunit PSMD11; FOXO4 regulates proteasome activity in hESCs by modulating PSMD11 expression, and the high proteasome activity decreases after induced differentiation.
