Data Sheet: 

Ubiquitin is a 76 amino acid (aa) protein that is ubiquitously expressed in all eukaryotic organisms. Ubiquitin is highly conserved with 96% aa sequence identity shared between human and yeast. In mammals, four ubiquitin genes encode for two ubiquitin­ribosomal fusion proteins and two polyubiquitin proteins.  Cleavage of the ubiquitin precursors by deubiquitinating enzymes gives rise to identical ubiquitin monomers each with a predicted molecular weight of 8.6 kDa.  Conjugation of ubiquitin to target proteins involves the formation of an isopeptide bond between the C-­terminal glycine residue of ubiquitin and a lysine residue in the target protein.  This process of conjugation, referred to as ubiquitination or ubiquitylation, is a multi­step process that requires three enzymes: a ubiquitin­activating (E1) enzyme, a ubiquitin­conjugating (E2) enzyme, and a ubiquitin ligase (E3). Ubiquitination is classically recognized as a mechanism to target proteins for degradation and as a result, ubiquitin was originally named ATP­dependent Proteolysis Factor 1 (APF­1).  In addition to protein degradation, ubiquitination has been shown to mediate a variety of biological processes such as signal transduction, endocytosis, and post­endocytic sorting.
