Researchers at National Taiwan University have uncovered, for the first time at atomic resolution, how the human proteasome recognizes branched ubiquitin chains. Their finding reveals a multivalent ...
The structure of a giant ubiquitin E3 ligase sheds light on its activation in a substrate-dependent manner and shows how a single E3 enzyme uses distinct recognition modules to confer substrate ...
Post-translational protein modifications by ubiquitin and ubiquitin-like modifiers regulate many major pathways in the cell. These modifications can be reversed by de-ubiquitinating enzymes such as ...
A team of international scientists has recently characterized the structure of tumor necrosis factor receptor associated factor 6 (TRAF6) N-terminal domain for therapeutic purposes. This protein is a ...
Small but powerful: Ubiquitin controls the lifespan and distribution of proteins in the cell, but it can also determine their shape, function, or interactions with other cellular components. Ubiquitin ...
