An interferon-stimulated gene (ISG) is a gene that can be expressed in response to stimulation by interferon. [1] [2] Interferons bind to receptors on the surface of a cell, initiating protein signaling pathways within the cell. This interaction leads to the expression of a subset of genes involved in the innate immune system response. [1]
The type-I interferons (IFN) are cytokines which play essential roles in inflammation, immunoregulation, tumor cells recognition, and T-cell responses. In the human genome, a cluster of thirteen functional IFN genes is located at the 9p21.3 cytoband over approximately 400 kb including coding genes for IFNα (IFNA1, IFNA2, IFNA4, IFNA5, IFNA6, IFNA7, IFNA8, IFNA10, IFNA13, IFNA14, IFNA16 ...
It took another fifteen to twenty years, using somatic cell genetics, to show that the interferon action gene and interferon gene reside in different human chromosomes. [71] [72] [73] The purification of human beta interferon did not occur until 1977. Y.H. Tan and his co-workers purified and produced biologically active, radio-labeled human ...
Stimulator of interferon genes (STING), also known as transmembrane protein 173 (TMEM173) and MPYS/MITA/ERIS is a protein that in humans is encoded by the STING1 gene. [ 5 ] STING plays an important role in innate immunity .
ISG15 was originally identified in the late 1970s as a 15-kDa protein produced in response to type I interferon, a potent class of antiviral cytokines. [19] Given the molecular weight, it was originally termed "a 15-kDa protein", but later renamed interferon-stimulated-gene-15 when the cassette of interferon-stimulated genes were recognized.
The best known example of the enhanceosome acts on the human interferon-beta gene, which is upregulated in cells that are infected by viruses. [5] Three activator proteins— NF-κB , an interferon activator protein such as IRF-3 , and the ATF -2/c-Jun complex—cooperatively bind to the upstream enhancer region upon viral infection.
IFNAR agonism results in transcriptional changes, with the potential to increase or suppress the transcription of over 2000 different genes. [9] For example, type I IFNs induce interferon-stimulated gene expression, classically resulting in a robust anti-viral immune
The gene encoding IFNα2, the IFNA2 gene, is clustered with all other type I IFN genes on chromosome 9 [8] and as all type I IFN genes, it is devoid of intron. [9] The open reading frame (coding sequence) of IFNA2 codes for a pre-protein of 188 amino acids with a 23 amino acid signal peptide allowing secretion of the mature protein. The mature ...
