Target Information
Ubiquitin-like protein ISG15 plays a key role in the innate immune response to viral infection either via its conjugation to a target protein (ISGylation) or via its action as a free or unconjugated protein. It is secreted from monocytes in response to type I interferons and causes natural killer (NK)-cell proliferation and augmentation of non-MHC-restricted cytotoxicity.
Synthesis is stimulated by IFN-alpha, IFN-beta, or IFN-omega, but not IFN-gamma. ISG15 expression is also induced by overexpression of interferon regulatory factors and by influenza B virus. It is secreted by monocyte, T-lymphocyte, B-lymphocyte, fibroblast, and epithelial cell lines.
Enhancement of NK cell proliferation and induction of IFN-gamma from T cells identify ISG15 as a cytokine-like factor that amplifies immunomodulatory effects of type I interferons. Mutations in ISG15 can result in Immunodeficiency 38 with basal ganglia calcification (IMD38).
