Background

Covalent conjugation to ubiquitin (Ub) is one of the major post-translational modifications that regulates protein stability, function, and localization. Ubiquitination is the concerted action of three enzymes: a Ub-activating enzyme (E1), a Ub-conjugating enzyme (E2), and a Ub ligase (E3). The specificity and efficiency of ubiquitination are largely determined by the E3 enzyme, which directs the last step of the Ub-conjugating cascade by binding to both an E2∼Ub conjugate and a substrate protein. This step ensures the transfer of Ub from E2∼Ub to the substrate, leading to its mono- or poly-ubiquitination. Methylated ubiquitin is a derivative of ubiquitin where the lysine residues have undergone methylation. It can bind to substrates and block the formation of polyubiquitination chains.
