| Source | Rabbit | | Reactivity | Human | | Background | Ubiquitinating enzymes catalyze protein ubiquitination, a reversible process countered by deubiquitinating enzyme action. Five DUB subfamilies are recognized, including the USP, UCH, OTU, MJD, and JAMM enzymes. USP18 is a deubiquitinase best known for catalyzing the removal of ISG15, an interferon-regulated ubiquitin-like protein, from conjugated proteins. Removal of ISG15 from target proteins by the USP18 peptidase maintains the critical cellular balance of ISG15-conjugated proteins important for normal development and brain function. Following induction by IFN or LPS, USP18 binds the INF receptor subunit IFNAR2 and inhibits signal transduction through the Jak/Stat pathway. USP18 regulation of IFN signaling inhibits IFN-mediated apoptosis and does not necessarily rely on USP18 peptidase activity. As the therapeutic use of recombinant IFN can lead to refractory IFN signaling and a less effective response, the combination of IFN treatment and regulation of USP18 expression may produce a more positive outcome. | | References | [1] Nijman, S.M. et al.
