Applications and conditions

Where to start

These starting conditions come from the recommended dilution, validation images, and general assay practice. Titrate for your sample and detection system.

WB Conditions for WB
Recommended dilution 1:1000 - 1:5000
Suggested sample / positive control HepG2,Mouse liver
Key conditions Use a fresh lysate, incubate at the recommended dilution, and check the predicted and observed molecular weight
Expected result Expected signal or band near 34KDa
Controls Include a positive sample, a negative sample, and a secondary or isotype control
IHC Conditions for IHC
Recommended dilution 1:50 - 1:200
Suggested sample / positive control HepG2,Mouse liver
Key conditions For paraffin sections, optimize retrieval buffer pH, retrieval time, and primary incubation
Expected result Expected localization: cytosol,nucleus
Controls Include a positive sample, a negative sample, and a secondary or isotype control
IF/ICC Conditions for IF/ICC
Recommended dilution 1:50 - 1:200
Suggested sample / positive control HepG2,Mouse liver
Key conditions Optimize fixation, permeabilization, and blocking, and include a secondary-only control
Expected result Expected fluorescence localization: cytosol,nucleus
Controls Include a positive sample, a negative sample, and a secondary or isotype control

Target data

Background The protein encoded by this gene belongs to the ubiquitin-specific proteases (UBP) family of enzymes that cleave ubiquitin from ubiquitinated protein substrates. It is highly expressed in liver and thymus, and is localized to the nucleus. This protein efficiently cleaves only ISG15 (a ubiquitin-like protein) fusions, and deletion of this gene in mice results in a massive increase of ISG15 conjugates in tissues, indicating that this protein is a major ISG15-specific protease. Mice lacking this gene are also hypersensitive to interferon, suggesting a function of this protein in downregulating interferon responses, independent of its isopeptidase activity towards ISG15.
Gene ID 11274
Gene name USP18
Swiss Q9UMW8
Synonym USP18,ISG43,UBP43,PTORCH2,USP18 Rabbit pAb,43 kDa ISG15-specific protease,ISG15-specific-processing protease,Ubl thioesterase 18
Functions Involved in the regulation of inflammatory response to interferon type 1 (PubMed:27325888). Can efficiently cleave only ISG15 fusions including native ISG15 conjugates linked via isopeptide bonds. Necessary to maintain a critical cellular balance of ISG15-conjugated proteins in both healthy and stressed organisms.
