USP14 inhibits ER. 4 / 4
| 4

reach
"At the molecular level, we find that inhibition of USP14 rapidly triggers accumulation of poly-ubiquitinated proteins and chaperones, mitochondrial dysfunction, ER stress, and a ROS production leading to a caspase independent cell death."

reach
"Although the physiological role of USP14 mediated inhibition of ERAD must be elucidated, USP14 may serve as a physiological regulator of ERAD to prevent the unnecessary leak of the ER luminal proteins[MISSING/INVALID CREDENTIALS: limited to 200 char for Elsevier]"

reach
"To further investigate whether the ESIs previously reported effect on protein translocation contributed to its inhibitory effect on IL-1 release or whether it was due to an inhibition of DUBs, we investigated the effects of a selective DUB inhibitor b-AP15 and of the protein translocation inhibitor cpd A. b-AP15 is a small molecule DUB inhibitor of the proteasome associated DUBs UCH37 and USP14, whereas cpd A is a selective inhibitor of the ER translocon with no effect on DUB activity."

"USP14 inhibits ER associated degradation via interaction with IRE1alpha."
