    Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Gly50 of mouse USP18 protein.

    Background

    Ubiquitinating enzymes (UBEs) catalyze protein ubiquitination, a reversible process countered by deubiquitinating enzyme (DUB) action. Five DUB subfamilies are recognized, including the USP, UCH, OTU, MJD, and JAMM enzymes (1,2). USP18 (also known as UBP43) is a deubiquitinase best known for catalyzing the removal of ISG15, an interferon-regulated ubiquitin-like protein, from conjugated proteins (3). 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 (4,5). Following induction by IFN or LPS (6), USP18 binds the INF receptor subunit IFNAR2 and inhibits signal transduction through the Jak/Stat pathway (7). USP18 regulation of IFN signaling inhibits IFN-mediated apoptosis and does not necessarily rely on USP18 peptidase activity (8). 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 (9).
