Specifications

Poly-ubiquitylation of target proteins through linkage at K48, is now the most thoroughly studied of the various chain linkages, and we once considered the hallmark of this post-translational modification. It is now clear that many, if not all, poly-Ub chain topologies likely play distinct and important roles in regulating cellular processes. Nevertheless, the K48 linkage remains a critical pathway for cells to maintain homeostasis through proteolytic degradation, and as such remains very intriguing for the study of DUBs that play a role in the degradation, as well as the proteasome itself. These diubiquitin chains generated from the enzymatic linkage of wild-type ubiquitin through lysine 48. The most distal ubiquitin contains an arginine substitution for the lysine at position 48, limiting chain length.
