ISGs are genes whose expression can be stimulated by interferon, but may also be stimulated by other pathways. [1] Interferons are a type of protein called a cytokine, which is produced in response to infection. [9] When released, they signal to infected cells and other nearby cells that a pathogen is present. [9]
Interferome is an online bioinformatics database of interferon-regulated genes (IRGs). [1] These Interferon Regulated Genes are also known as Interferon Stimulated Genes (ISGs). The database contains information on type I (IFN alpha, beta), type II (IFN gamma) and type III (IFN lambda) regulated genes and is regularly updated.
Interferon-stimulated gene 15 (ISG15) is a 17 kDa secreted protein that in humans is encoded by the ISG15 gene. [ 5 ] [ 6 ] ISG15 is induced by type I interferon (IFN) and serves many functions, acting both as an extracellular cytokine and an intracellular protein modifier.
STAT1 homodimers are involved in type II interferon signalling, and bind to the GAS (Interferon-Gamma Activated Sequence) promoter to induce expression of interferon stimulated genes (ISG). In type I interferon signaling, STAT1-STAT2 heterodimer combines with IRF9 (Interferon Response Factor) to form ISGF3 (Interferon Stimulated Gene Factor ...
Upon activation, STING stimulates TBK1 activity to phosphorylate IRF3 or STAT6. Phosphorylated IRF3s and STAT6s dimerize, and then enter nucleus to stimulate expression of genes involved in host immune response, such as IFNB, CCL2, CCL20, etc. [8] [23] Several reports suggested that STING is associated with the activation of selective autophagy ...
Interferon-induced protein with tetratricopeptide repeats 3, also known as interferon-stimulated gene 49 ... is a protein that in humans is encoded by the IFIT3 gene. ...
Viperin is an interferon-stimulated gene whose expression inhibits many DNA and RNA viruses including CHIKV, HCMV, HCV, DENV, WNV, SINV, influenza, and HIV. [6] Initially identified as an IFN-γ induced antiviral protein in human cytomegalovirus (HCMV) infected macrophages, it was reported that viperin could be induced by HCMV glycoprotein B in fibroblasts, but inhibits HCMV viral infection ...
Interferon-induced protein with tetratricopeptide repeats 2 (commonly termed IFIT2) is a protein that in humans is directed to be produced by the IFIT2 gene. [5] [6] [7] Previously, this gene was termed the G10P2, GARG-39, IFI-54, IFI-54K, IFI54, IFIT-2, ISG-54 K, ISG-54K, ISG54, or P54 gene and the protein that it directs to be produced was termed the G10P2, GARG-39, IFI-54, IFI-54K, IFI54 ...
