该基因编码的蛋白质属于irf（interferon regulatory factor）转录因子家族，具有独特的色氨酸五肽重复序列dna结合域。irfs在调节干扰素对病毒感染的应答和调节干扰素诱导基因方面具有重要作用。这个家族成员是淋巴细胞特异性的，负性调节toll样受体（tlr）信号，这是激活先天性和适应性免疫系统的核心。涉及该基因和igh基因座t（6；14）（p25；q32）的染色体易位可能是多发性骨髓瘤的病因。另外，已经发现该基因的剪接转录变体。[由RefSeq提供，2010年8月]
The protein encoded by this gene belongs to the IRF (interferon regulatory factor) family of transcription factors, characterized by an unique tryptophan pentad repeat DNA-binding domain. The IRFs are important in the regulation of interferons in response to infection by virus, and in the regulation of interferon-inducible genes. This family member is lymphocyte specific and negatively regulates Toll-like-receptor (TLR) signaling that is central to the activation of innate and adaptive immune systems. A chromosomal translocation involving this gene and the IgH locus, t(6;14)(p25;q32), may be a cause of multiple myeloma. Alternatively spliced transcript variants have been found for this gene.
