reach
"USP4 deubiquitinates TAK1 in vivo and in vitro."

reach
"85 The deubiquitinating enzyme ubiquitin‐specific protease 4 (USP4) attenuates major hypertrophic signalling pathways, such as TAK1‐JNK and TAK1‐p38, by removing the K63‐linked polyubiquitination of TAK1."

"Using a functional genomic approach, we have identified ubiquitin-specific peptidase 4 (USP4) as a deubiquitinase for TAK1."

reach
"In addition, USP4 inhibits TNF-alpha-induced activation of NF-kappaB through USP4 deubiquitination of TAK1 XREF_BIBR."

reach
"Although it has been reported that USP4 deubiquitinates TAK1 and negatively regulates TNF- and IL-1-induced activation of NF-kappaB, how TAK1 ubiquitination is regulated in adaptive immune cells such as T cells and whether such a regulation regulates T cell mediated immune response remain unknown."

reach
"In view of the data presented here and previous reports, we propose a working model (XREF_FIG), in which that TNFalpha rapidly induces Lys63 linked TAK1 polyubiquitnation and binding of USP4 to TAK1, Lys63 linked TAK1 would be rapidly deubiquitinated by USP4 to attenuate the magnitude of TNFalpha induced Lys63 linked TAK1 polyubiquitination and TAK1 mediated IKK and NF-kappaB activation."

reach
"In conclusion, our results provide evidence that TNFalpha induces association of USP4 with TAK1 which leads to TAK1 deubiquitination in the TNFalpha mediated NF-kappaB activation."

reach
"After TAK1 is activated with Lys63 linked polyubiquitination by Dox, USP4 deubiquitinates TAK1 and inhibits TAK1 mediated signaling."

reach
"Moreover, p38IP scaffolds the deubiquitinase USP4 to deubiquitinate TAK1 once TAK1 is activated."

"USP4 inhibits p53 and NF-kappaB through deubiquitinating and stabilizing HDAC2."

reach
"Taken together, our results suggested that TRPS1 stabilized HDAC2 by functioning as a scaffold protein to bring UPS4 and HDAC2 together forming the TRPS1-UPS4-HDAC2 complex to enhance USP4-directed HDAC2 de-ubiquitination."

reach
"Another DUB, USP4 deubiquitinates HDAC2 (Histone deacetylases 2) that was shown to interact with p53 thereby inhibiting the level of acetylated p53."

reach
"XREF_BIBR, XREF_BIBR Of note, our studies show that USP4 deubiquitinates and stabilizes HDAC2 and the expression of USP4 correlates with that of HDAC2 in cancer tissues (XREF_FIG)."

reach
"Although USP4 alone could reduce HDAC2 ubiquitination level, additional overexpression of TRPS1 significantly enhanced the reduction of HDAC2 ubiquitination (Fig. 3l)."

reach
"As we demonstrated that USP4 deubiquitinates HDAC2, it is possible that USP4 can stabilize HDAC2."

reach
"Nonetheless, USP4 might deubiquitinate and stabilize both ARF-BP1 and its substrate HDAC2."

reach
"However, the mechanism by which USP4 mediates HDAC2 de-ubiquitination contributing to cancer remains unclear.In this study, we show that the TRPS1-USP4-HDAC2 regulatory axis is involved in tumor cell proliferation."

reach
"Significantly, our results revealed the scaffolding function of TPRS1 in USP4-directed HDAC2 de-ubiquitination and provided new mechanistic insights into the crosstalk between TRPS1, ubiquitin, and histone modification systems leading to tumor growth."

reach
"Furthermore, our results identified the novel non-transcription factor scaffolding function of the GATA family member TRPS1 in USP4-directed HDAC2 de-ubiquitination."
