Ubiquitin D is a protein that in humans is encoded by the UBD gene, also known as FAT10. [ 5 ] [ 6 ] [ 7 ] UBD acts like ubiquitin , by covalently modifying proteins and tagging them for destruction in the proteasome.
Ubiquitin is a small (8.6 kDa) regulatory protein found in most tissues of eukaryotic organisms, i.e., it is found ubiquitously.It was discovered in 1975 [1] by Gideon Goldstein and further characterized throughout the late 1970s and 1980s. [2]
Mdm2 also acts as an E3 ubiquitin ligase, targeting both itself and p53 for degradation by the proteasome (see also ubiquitin). Several lysine residues in p53 C-terminus have been identified as the sites of ubiquitination, and it has been shown that p53 protein levels are downregulated by Mdm2 in a proteasome-dependent manner. Mdm2 is capable ...
The NMR structure of a UBA domain, among the most common types of ubiquitin-binding domain, from the protein ubiquilin-1 (top, cyan) bound to ubiquitin (bottom, orange). ). Isoleucine 44, the center of a hydrophobic patch on the ubiquitin surface that interacts with a number of ubiquitin-binding domains, is highlighted i
The ubiquitin-proteasome system is critical to appropriate protein degradation within cells. Dysfunctions of this system can disrupt cellular homeostasis and lead to a host of disorders. In normally functioning cells, the covalent linkage of ubiquitin or ubiquitin-like protein to a target protein changes the target protein's surface.

E3 ubiquitin-protein ligase NEDD4, also known as neural precursor cell expressed developmentally down-regulated protein 4 (whence "NEDD4") is an enzyme that is, in humans, encoded by the NEDD4 gene. [5] [6] NEDD4 is an E3 ubiquitin ligase enzyme, that targets proteins for ubiquitination. [7]
Ubiquitin-associated (UBA) domains are protein domains that non-covalently interact with ubiquitin through protein-protein interactions. Ubiquitin is a small protein that is covalently linked to other proteins as part of intracellular signaling pathways, often as a signal for protein degradation .
