Interferon regulatory factor 3

Interferon Regulatory Factor-3, IRF-3
This gene encodes a member of the interferon regulatory transcription factor (IRF) family. The encoded protein is found in an inactive cytoplasmic form that upon serine/threonine phosphorylation forms a complex with CREBBP. This complex translocates to the nucleus and activates the transcription of interferons alpha and beta, as well as other interferon-induced genes. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene. [provided by RefSeq, Nov 2011] (from NCBI)

Shadel et al., New Haven, United States. In Nature, May 2015
Mechanistically, we find that aberrant mtDNA packaging promotes escape of mtDNA into the cytosol, where it engages the DNA sensor cGAS (also known as MB21D1) and promotes STING (also known as TMEM173)-IRF3-dependent signalling to elevate interferon-stimulated gene expression, potentiate type I interferon responses and confer broad viral resistance.

Chen et al., Dallas, United States. In Science, Apr 2015
Phosphorylated MAVS and STING then bind to a positively charged surface of interferon regulatory factor 3 (IRF3) and thereby recruit IRF3 for its phosphorylation and activation by TBK1.

Such mechanisms engage signaling cascades which, in the initial phase of infection, lead to the activation of the NF-κB pathway and IFN regulatory factors (IRF-3, IRF-7) which directly control the production of IFNs.
