The receptor and interferon are taken inside the cell while bound to initiate expression of ISGs. [10] Interferon activation of ISGs uses the JAK-STAT signaling pathway to induce transcription of ISGs. ISGs can be divided based on what class of interferon they are activated by: type I, type II, or type III interferon. [1] The protein products ...
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 ...
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.
STING induces type I interferon production when cells are infected with intracellular pathogens, such as viruses, mycobacteria and intracellular parasites. [6] Type I interferon, mediated by STING, protects infected cells and nearby cells from local infection by binding to the same cell that secretes it (autocrine signaling) and nearby cells ...
Interferon gamma (IFNG or IFN-γ) is a dimerized soluble cytokine that is the only member of the type II class of interferons. [5] The existence of this interferon, which early in its history was known as immune interferon, was described by E. F. Wheelock as a product of human leukocytes stimulated with phytohemagglutinin, and by others as a product of antigen-stimulated lymphocytes. [6]
For example, type I IFNs induce interferon-stimulated gene expression, classically resulting in a robust anti-viral immune response. Additionally, IFNs largely impact cell health and viability, with effects on apoptosis, autophagy, cell differentiation, and proliferation. [10]
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.
