The IFIT family is commonly induced by type I and type III interferon. [3] [5] IFIT gene expression has been observed in response to both DNA and RNA viral infection. IFIT genes suppress viral infection primarily by limiting viral RNA and DNA replication. [5] IFIT proteins 1,2,3 and 5 can bind directly to double-stranded triphosphate RNA.
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.
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. It is used by the interferon and cytokine research community [2] both as an analysis tool and an information ...
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 ...
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 ...
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 .
For a bonus, Kaiser recommends making your workout a "dance routine, as studies indicate that exercises that combine physical and cognitive challenges can especially improve memory and brain health."
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 ...
