Description
Catalogue Number 17-10388
Brand Family Chemicon®
Trade Name
  • Chemicon
Description Di-Ubiquitin (Lys63-linked) Recombinant Protein
Overview ANTIBODY AVAILABLE!
Anti-Ubiquitin, Lys63-Specific, clone Apu3 ( catalogue # 05-1308)

This product is a native K63 linked Di-Ubiquitin which can be used as a substrate for proteases that cleave the isopeptide linkage between two ubiquitin molecules. It can also be used to investigate mechanism of binding and recognition by proteins that contain ubiquitin-associated domains or ubiquitin-interacting motifs (UIMs).
This product is formed by chemical ligation.
Background Information Polyubiquitin chains linked through the Lys48 residue of ubiquitin are most commonly associated with proteins targeted for proteosomal degradation.

In contrast, polyubiquitin chains linked through the Lys63 residue of ubiquitin (Ub) are associated with nonproteolytic functions such as signal transduction. Lys63-linked polyUb chains connect components of NFκB signaling in a highly regulated manner, and genetic evidence indicates the involvement of Lys63-linked Ub chains in stress response and DNA repair. Research in yeast has suggested Lys63-linked Ub chains stimulate endocytosis.
