IRF2 encodes interferon regulatory factor 2, a member of the interferon regulatory transcription factor (IRF) family. IRF2 competitively inhibits the IRF1-mediated transcriptional activation of interferons alpha and beta, and presumably other genes that employ IRF1 for transcription activation. However, IRF2 also functions as a transcriptional activator of histone H4. [provided by RefSeq, Jul 2008]
Forensic Context
A study in mice demonstrated that chronic methamphetamine administration significantly upregulated the transcription factor IRF2 in cortical astrocytes, as identified through single-cell RNA sequencing analysis [Oladapo et al. DOI:10.3390/Ijms26020649].
