PSMD14 affects E2F1
| 8
PSMD14 deubiquitinates E2F1. 8 / 8
| 8

reach
"This finding led us to hypothesize that POH1 may interact with and deubiquitinate E2F1."

reach
"Our present study provides evidence that POH1 deubiquitinates and stabilizes the master transcription factor E2F1 and functions as a tumour promoting protein in HCCs."

reach
"We propose that the deubiquitination of E2F1 by POH1 primarily occurs in the nucleus; as a consequence, the prosurvival genes, including Survivin and FOXM1, are transcriptionally activated."

reach
"POH1 knockdown significantly enhanced the levels of E2F1 ubiquitination (XREF_FIG)."

reach
"We demonstrated that POH1 efficiently deubiquitinates E2F1 by removing the K-63 polyubiquitin chains, and this observation is consistent with previous studies revealing that the JAMM domain within POH1 is responsible for removing K63 linked ubiquitin chains XREF_BIBR XREF_BIBR XREF_BIBR."

reach
"In addition, in MG132 treated cells, wherein the global proteasomal activity was inhibited, ectopic POH1 expression was able to deubiquitinate E2F1 (XREF_SUPPLEMENTARY), suggesting that this effect is independent of the overall proteasome function."

reach
"Of note, although E2F1 deubiquitination by POH1 has been revealed to be important for E2F1 stabilization, the molecular details of the regulation remain to be defined."

reach
"In line with our results, a previous study revealed that POH1, a deubiquitinase, binds to and deubiquitinates E2F1, contributing to its stabilization."

reach

| 2
Modified PSMD14 leads to the deubiquitination of JUN. 2 / 2
| 2

reach
"Ectopic expression of POH1 in HEK293 cells decreased the level of c-Jun ubiquitination, leading to significant accumulation of the protein and a corresponding increase in AP1 mediated gene expression."

reach
"A previous study indicated that POH1 overexpression in HEK293 cells downregulates c-Jun ubiquitination, resulting in c-Jun accumulation and upregulation of AP1 mediated gene expression XREF_BIBR."

reach

reach
"Mechanistically, POH1 deubiquitinates the TGF-beta receptors and CAV1, therefore negatively regulates lysosome pathway mediated turnover of TGF-beta receptors."

"Second, proteasomal Poh1 possesses a K63 specific deubiquitinating enzyme activity, which is required for activating aggresome clearance (XREF_FIG)."
PSMD14 affects proIL‐1β
| 1
PSMD14 deubiquitinates proIL‐1β. 1 / 1
| 1

reach
"In line with this work, Zhang et al.81 have shown that POH1, a DUB that forms part of the 19S subunit of the proteasome, interacts with and deubiquitinates proIL‐1β by decreasing the K63‐linked polyubiquitin chains, as well as decreasing the efficacy of proIL‐1β cleavage."

PSMD14 deubiquitinates pro-IL-1β. 1 / 1

reach
"POH1 deubiquitinates pro-IL-1β and inhibits mature IL-1β production, thus restricting inflammasome activity and LPS-induced inflammation [93]."

| 1
PSMD14 leads to the deubiquitination of bortezomib. 1 / 1

reach
"Together with the finding that POH1 inhibition induced a distinctly different change in the ubiquitination profile from bortezomib, this compound may have potential as a treatment modality in patients previously treated with bortezomib."
