    ..Taken together, our data demonstrate that Jab1 is an important effector that mediates a novel signal transduction pathway for PAR-2-dependent gene expression. ..

    ..This suggests that the propensity of the CSN complex to change and adapt its subunit composition might underlie its ability to perform multiple functions in vivo. ..

    ..Our results suggest that specificity for K63-linked polyubiquitin is a common property of the JAMM/MPN+ family of DUBs. ..

    ..These findings suggest that Jab1 provides a novel signal transduction pathway for 5-HT(6)R and may play an important role in 5-HT(6)R-mediated behavior changes in the brain. ..

    ..These data indicate that D-DT is a MIF-like cytokine with an overlapping spectrum of activities that are important for our understanding of MIF-dependent physiology and pathology. ..

    ..We propose that COP9-associated CSN5 regulates exosomal protein sorting in both a deubiquitinating activity-dependent and -independent manner, which is contrary to the current idea of ubiquitin-dependent sorting of proteins to exosomes. ..

    ..Retrieval of surface-stranded synaptotagmin 1 is restored by overexpression of stonin 2 in ?E-TA-expressing cells, suggesting that the DYT1 mutation compromises the role of TA in protein stabilisation and synaptic vesicle recycling. ..

    ..These results suggested that JAB1 may act as a key molecule in selecting the UPR or cell death by association and dissociation with IRE1alpha. ..

    ..Thus, Jab1 controls cell cycle progression and cell survival by regulating multiple cell cycle signaling pathways. ..
