IRF2（interferon regulatory factor 2），癌症关联基因，基因ID：3660，irf2编码干扰素调节因子2，是干扰素调节转录因子（irf）家族的成员。irf2竞争性地抑制irf1介导的干扰素α和β的转录激活，可能还有其他利用irf1进行转录激活的基因。然而，irf2也可以作为组蛋白h4的转录激活物。[由RefSeq提供，2008年7月]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]。
