Usp18 Gene Summary [Rat]
Predicted to enable ISG15-specific peptidase activity; cysteine-type deubiquitinase activity; and molecular adaptor activity. Predicted to be involved in several processes, including antiviral innate immune response; regulation of defense response; and response to stilbenoid. Predicted to act upstream of or within response to bacterium. Predicted to be located in intracellular membrane-bounded organelle. Predicted to be active in cytosol and nucleus. Orthologous to several human genes including USP18 (ubiquitin specific peptidase 18). [provided by Alliance of Genome Resources, Apr 2025]

Protein Domains
A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in rat Usp18 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
