Mouse (Murine) Ubiquitin Specific Peptidase 18 (USP18) interaction partners

1. Usp18 protects the cells from oxidative stress-induced apoptosis which may be through the regulation of p53 and caspase 3.

2. associates with and deubiquitinates TAK1 to protect against hepatic steatosis, insulin resistance, and the inflammatory response

3. this study identifies the osteopenia phenotype of mice lacking Usp18, which is known as a negative regulator of type I IFN signaling

5. USP18's ISG15 specificity is mediated by a small interaction interface.

6. findings show that multiple inflammatory stimuli can modulate interferon stimulated gene expression and thus inhibit hepatocyte interferon signaling via USP18 induction

7. Increased ISGylation was accompanied by enhanced viral resistance without causing detrimental side effects suggesting that USP18 protease inhibition might be a suitable antiviral strategy

8. USP18 null mice develop leiomyosarcoma recapitulating key features of clinical leiomyosarcomas and patients with reduced-USP18 tumor levels have an unfavorable outcome.

9. USP18 lack in microglia causes destructive interferonopathy of the mouse brain.

10. results suggest that increasing ISGylation by specific inhibition of USP18 protease activity could constitute a promising antiviral strategy with only a minimal risk of severe adverse effects

11. USP18 is crucial for IFN-gamma-mediated inhibition of B16 melanoma tumorigenesis and antitumor immunity.
