Our in vivo and in vitro ubiquitylation studies demonstrate that the binding of TSG101 to Mahogunin targets the substrate TSG101 for ubiquitylation by Mahogunin E3 ligase in cooperation with its cognate E2 enzyme Ubc5a |

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 t |

In the present study, we identified the first substrate of the Mahogunin E3 ubiquitin–protein ligase: TSG101, a key component of the endosomal sorting ESCRT machinery.We find that Mahogunin interacts with the ubiquitin E2 variant (UEV) domain of TSG101 via its PSAP motif and that it catalyzes monoubiquitylation of TSG101 both in vivo and in vitro. Consistent with the results of the biochemical characterization and subcellular localization studies of Mahogunin, our functional studies provide direct evidence that Mahogunin plays an essential role in regulation of endosome-to-lysosome trafficking. We found that siRNA-mediated depletion of Mahogunin in HeLa cells causes enlargement and clustering of EEA1-positive endosomes and LAMP2-positive late endosomes/lysosomes (Figure 8B) and inhibits the endosomal trafficking of internalized EGF–EGFR complexes to lysosomes for degradation (Figures 9 and and10,10, A and B). These results are strikingly similar to the phenotypes that resulted from depletion of TSG101 |
