| 背景信息 | Ubiquitin protein ligase E3 component n-recognin 1 (UBR1) is a large multifunctional E3 ubiquitin ligase that serves as a primary component of the N-end rule pathway. It recognizes and binds proteins with specific destabilizing N-terminal residues, targeting them for ubiquitination and subsequent proteasomal degradation. UBR1 features multiple substrate-binding sites and associates with E2 ubiquitin-conjugating enzymes such as Ubc2/Rad6 and Ubc4. In addition to its role in the N-end rule pathway, it functions in the quality control of misfolded cytosolic proteins, a process facilitated by Hsp70 chaperones. UBR1 is broadly expressed in human tissues, including the brain, liver, and pancreas. Mutations in the UBR1 gene are the established cause of Johanson-Blizzard syndrome, a rare autosomal recessive disorder characterized by exocrine pancreatic insufficiency and various congenital malformations. |
