CSN5 directly bound survivin and decreased its ubiquitination to enhance the protein stability of survivin.
verexpression of COPS5, through its isopeptidase activity, leads to ubiquitination and proteasome-mediated degradation of NCoR, a key corepressor for ERalpha and tamoxifen-mediated suppression of ERalpha target genes.
These findings provide novel insights into molecular mechanism of let-7d and Jab1 in tumor development and progression of breast cancer, and thus let-7d/Jab1 are novel potential therapeutic targets for breast cancer patients.
We identified a novel Jab1-Trx axis that is a key cellular process in the pathobiologic characteristics of acute myeloid leukemia (AML-M5). Targeting the ROS/Jab1/Trx pathway could be beneficial in the treatment of AML-M5
These data identified CSN5 as a critical oncoprotein involved in progression of hepatocellular carcinoma (HCC) cells, which could serve as a potential therapeutic target in HCC patients.
The authors find that UCHL3 regulates COPS5-dependent deneddylation of Cullin1, which is an essential component of SCF(beta-TrCP) complex and associated with SCF(beta-TrCP) activities. The authors further demonstrate that UCHL3 upregulates the levels of SCF(beta-TrCP) substrates including IFN-I receptor IFNAR1, which enhances IFN-I mediated signaling pathway and antiviral activity.
Collectively, our findings suggest that JAB1 activates the neuronal differentiation ability of CPNE1 through the binding of C2A domain in CPNE1 with MPN domain in JAB1.

CSN5 is contributed to colorectal cancer development by actively driving aberrant WNT signaling through repression of the WNT antagonist DKK1.
The results of this study suggest that Jab1 promotes glioma cell proliferation and increased expression of Jab1 in glioma patients may amplify beta-catenin signaling to contribute to glioma cell proliferation.
Furthermore, inhibition of COPS5 resulted in an elevation of Akt expression and sensitized SOC cells to Akt inhibitor MK2206. Suppression of COPS5 and Akt offers a potential strategy for the treatment of SOC.

We found that increased expression of JAB1 promoted odontogenic differentiation of DPSCs via Wnt/beta-catenin signaling. The role of JAB1 in the odontogenic differentiation of DPSCs was further confirmed by knocking down JAB1. Our findings provide novel insights on odontogenic differentiation of DPSCs.

The protein encoded by this gene is one of the eight subunits of COP9 signalosome, a highly conserved protein complex that functions as an important regulator in multiple signaling pathways. The structure and function of COP9 signalosome is similar to that of the 19S regulatory particle of 26S proteasome. COP9 signalosome has been shown to interact with SCF-type E3 ubiquitin ligases and act as a positive regulator of E3 ubiquitin ligases. This protein is reported to be involved in the degradation of cyclin-dependent kinase inhibitor CDKN1B/p27Kip1. It is also known to be an coactivator that increases the specificity of JUN/AP1 transcription factors.
