Here we report that ubiquitin is the genuine substrate of PINK1. PINK1 phosphorylated ubiquitin at Ser 65 both in vitro and in cells, and a Ser 65 phosphopeptide derived from endogenous ubiquitin was only detected in cells in the presence of PINK1 and following a decrease in mitochondrial membrane potential. |

The activation of ubiquitin by the ubiquitin-activating enzyme Uba1 (E1) constitutes the first step in the covalent modification of target proteins with ubiquitin. This activation is a three-step process in which ubiquitin is adenylated at its C-terminal glycine, followed by the covalent attachment of ubiquitin to a catalytic cysteine residue of Uba1 and the subsequent adenylation of a second ubiquitin. |

Here we provide data suggesting that two of the four mammalian ubiquitin precursors, UBA52 and UBA80, are processed mostly post-translationally whereas the other two, UBB and UBC, probably undergo a combination of co- and post-translational processing. Using an unbiased biochemical approach we found that UCHL3, USP9X, USP7, USP5 and Otulin/Gumby/FAM105b are by far the most active DUBs acting on these precursors. |

MHC class I antigen presentation pathway. Proteins with ubiquitin tags (red spheres) are degraded by proteasomes and the resulting peptides are transported into the endoplasmic reticulum (ER) by TAP|Many viruses have mechanisms of interfering with MHC class I processing, including direct interaction of viral proteins with immunoproteasome subunits. |

The ubiquitination process is mediated sequentially by three classes of enzymes consisting of a Ub-activating enzyme E1, a Ub-conjugating enzyme E2, and a Ub ligase E3. Ub is first activated by E1 in an adenosine 5′-triphosphate (ATP)-dependent manner to form a thioester-linked E1‒Ub conjugate. The activated Ub is then delivered to an E2 enzyme via a transthiolation reaction. Finally, an E3 enzyme, which can bind both a substrate and an E2‒Ub conjugate, mediates the covalent linkage of Ub to the target protein as a tag. |

The phosphorylation-dependent interaction between ubiquitin and parkin suggests that phosphorylated ubiquitin unlocks autoinhibition of the catalytic cysteine. Our results show that PINK1-dependent phosphorylation of both parkin and ubiquitin is sufficient for full activation of parkin E3 activity. These findings demonstrate that phosphorylated ubiquitin is a parkin activator. |
