One important proteolytic pathway involves the small protein ubiquitin (Ub) and the 26S proteasome, a 2-MDa protease complex. In this pathway, Ub is attached to proteins destined for degradation; the resulting Ub-protein conjugates are then recognized and catabolized by the 26S proteasome. This...
One major pathway is represented by the ubiquitin (Ub)/26S proteasomepathway. 植物的生长和发育离不开短命调控蛋白的有选择性降解,其中一种重要的降解方式就是泛素/26S蛋白酶体途径。 更多例句>> 3) 26S proteasome 26S蛋白酶复合体 1. The changes of26S proteasomelevel in skeletal muscle of the seve...

and signalling factors. The ubiquitin-proteasome pathway deconstructs most proteins in the eukaryotic cell cytosol and nucleus. Others are degraded via the vacuolar pathway which includes endosomes, lysosomes and the endoplasmic reticulum.The 26S proteasome is an ATP-dependent, multisubunit (~31), barr...

The ubiquitin–proteasome system (UPS) and macroautophagy (autophagy) are central to normal proteostasis and interdependent in that autophagy is known to compensate for the UPS to alleviate ensuing proteotoxic stress that impairs cell function. UPS and a
