Ubiquitin is a highly conserved 76kDa protein which is ligated to many proteins in both monomeric and polymeric forms. Ubiquitin polymers (polyubiquitin) can be found in several varieties depending on which of its 7 lysine residues is the site of ligation. The two most common polymer chains are linked via an isopeptide bond between glycine-76 and either lysine-48 (K-48) or lysine-63 (K-63). K-48-linked polyubiquitination typically results in targeting the protein to the 26S proteosome resulting in proteolysis, although recently exceptions to this have been observed. In contrast, K-63-linked polyubiquitination results in signals related to intracellular trafficking, cell signaling, ribosomal biogenesis, and DNA damage repair. There are also reports that K63-linked polyubiquitin is involved in proteosome-independent proteolysis via autophagy.
