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 |

We demonstrate that Hectd1 is a functional ubiquitin ligase and that one of its substrates is Hsp90, a chaperone protein with both intra- and extracellular clients. Identification of Hsp90 in both proteomic screens suggested that members of the Hsp90 superfamily may be substrates of Hectd1. Myc-Hectd1ANK and HA-Hsp90bd (the fragment identified in the yeast two-hybrid screen) bind in an in vitro binding assay (Fig. 3 D) and when coexpressed in HEK293T cells. Hectd1 is required for K63-linked Ubn of Hsp90. Together, these results demonstrate that Hectd1-dependent Ubn of Hsp90 targets it away from the membrane and the secretory pathway. |
