Background

Function：Ubiquitin-like protein which 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 (PubMed:27564865, PubMed:39465252). ISGylation involves a cascade of enzymatic reactions involving E1, E2, and E3 enzymes which catalyze the conjugation of ISG15 to a lysine residue in the target protein (PubMed:33727702). Its target proteins include IFIT1, MX1/MxA, PPM1B, UBE2L6, UBA7, CHMP5, CHMP2A, CHMP4B and CHMP6. Isgylation of the viral sensor IFIH1/MDA5 promotes IFIH1/MDA5 oligomerization and triggers activation of innate immunity against a range of viruses, including coronaviruses, flaviviruses and picornaviruses (PubMed:33727702). Can also isgylate: EIF2AK2/PKR which results in its activation, RIGI which inhibits its function in antiviral signaling response, EIF4E2 which enhances its cap structure-binding activity and translation-inhibition activity, UBE2N and UBE2E1 which negatively regulates their activity, IRF3 which inhibits its ubiquitination and degradation and FLNB which prevents its ability to interact with the upstream activators of the JNK cascade thereby inhibiting IFNA-induced JNK signaling. Exhibits antiviral activity towards both DNA and RNA viruses, including influenza A, HIV-1 and Ebola virus. Restricts HIV-1 and ebola virus via disruption of viral budding. Inhibits the ubiquitination of HIV-1 Gag and host TSG101 and disrupts their interaction, thereby preventing assembly and release of virions from infected cells. Inhibits Ebola virus budding mediated by the VP40 protein by disrupting ubiquitin ligase activity of NEDD4 and its ability to ubiquitinate VP40. ISGylates influenza A virus NS1 protein which causes a loss of function of the protein and the inhibition of virus replication. The secreted form of ISG15 can: induce natural killer cell proliferation, act as a chemotactic factor for neutrophils and act as a IFN-gamma-inducing cytokine playing an essential role in antimycobacterial immunity. The secreted form acts through the integrin ITGAL/ITGB2 receptor to initiate activation of SRC family tyrosine kinases including LYN, HCK and FGR which leads to secretion of IFNG and IL10; the interaction is mediated by ITGAL (PubMed:29100055)

Subcellular Localization：Cytoplasm; Secreted

Expression：
Tissue_specificity:This gene can be detected in lymphocytes, skeletal and smooth muscle, various epithelial cells, and neurons. It is expressed in neutrophils, monocytes, and lymphocytes. Compared to non-cancerous tissues, its expression is enhanced in pancreatic adenocarcinoma, endometrial cancer, and bladder cancer. In bladder cancer, increased gene expression is significantly positively correlated with disease progression.

Induction:Strongly induced upon exposure to type I interferons, viruses, LPS, and other stresses, including certain genotoxic stresses

Subunit：Homodimer; disulfide-linked (PubMed:2440890). Interacts with, and is conjugated to its targets by UBE1L (E1 enzyme) and UBE2E2 (E2 enzyme) (PubMed:11157743, PubMed:15131269). Interacts with NEDD4 (PubMed:18305167). Interacts with PARP12; this interaction inhibits PINK1/Parkin-dependent mitophagy (PubMed:39465252)
