WebJan 9, 2024 · An expansion in the gene regulatory repertoire controlled by JAK/STAT signaling occurs through the interaction of STATs with IRF transcription factors to form ISGF3, a complex that contains STAT1, STAT2, and IRF9 and regulates expression of IFN-stimulated genes. how to remove scratches from gold
The IRF Family Transcription Factors in Immunity and Oncogenesis
Interferon regulatory factors (IRF) are proteins which regulate transcription of interferons (see regulation of gene expression). Interferon regulatory factors contain a conserved N-terminal region of about 120 amino acids, which folds into a structure that binds specifically to the IRF-element (IRF-E) motifs, which is … See more IRFs primarily regulate type I IFNs in the host after pathogen invasion and are considered the crucial mediators of an antiviral response. Following a viral infection, pathogens are detected by Pattern Recognition Receptors See more In addition to the signal transduction functions of IRFs in innate immune responses, multiple IRFs (IRF1, IRF2, IRF4, and IRF8) play essential roles in the development of immune cells, including dendritic, myeloid, natural killer (NK), B, and T See more • IRF1 • IRF2 • IRF3 • IRF4 • IRF5 • IRF6 • IRF7 See more IRFs are critical regulators of immune responses and immune cell development, and abnormalities in IRF expression and function have been linked to numerous diseases.
