One variant encodes an endoplasmic reticulum (ER)-anchored DUB that rescues misfolded transmembrane proteins from ER-associated degradation (ERAD), but the underlying mechanism remains to be elucidated. Here, we show that USP19 interacts with the ERAD-associated E3 ubiquitin ligase MARCH6. Overexpression of USP19 delayed the degradation of MARCH6, leading to an increase in its protein level. In contrast, USP19 depletion resulted in decreased expression of MARCH6. We also show that USP19 overexpression reduced ubiquitination of MARCH6, while its knockdown had the opposite effect. In particular, USP19 was found to protect MARCH6 by deubiquitination from the p97-dependent proteasomal degradation. In addition, USP19 knockdown leads to increased expression of mutant ABCB11, an ERAD substrate of MARCH6. Moreover, USP19 is itself subjected to endoproteolytic processing by DUB activity, and the processing cleaves off an N-terminal cytoplasmic region of unknown function. However, elimination of this processing had no evident effect on MARCH6 stabilization. These results suggest that USP19 is involved in the regulation of ERAD by controlling the stability of MARCH6 via deubiquitination."xsd:string |
