Interferon (IFN)‐inducible 44 like (IFI44L) is an IFN‐stimulated gene, the expression of which is induced by IFN and human immunodeficiency virus (HIV)‐1 infection. However, the mechanism has not yet been determined. In this study, we cloned the promoter of the IFI44L gene and found that interferon regulatory factor‐1 could bind directly to the IFN‐stimulated response element in the IFI44L promoter to activate IFI44L. Furthermore, we demonstrated that HIV‐1 can activate the IFI44L promoter to influence the expression of IFI44L. Interferon (IFN)‐inducible 44 like (IFI44L) is an IFN‐stimulated gene (ISG), which is located on the same chromosome as the known antiviral ISG IFI44. Expression of IFI44L is induced by IFN and HIV‐1 infection. However, the mechanism by which IFN‐I induces IFI44L production has not yet been determined. In this study, we analyzed transcriptional regulation of IFI44L via cloning of the IFI44L promoter. We found that IFI44L has two IFN‐stimulated response elements (ISRE), which are necessary for the basal level of IFI44L transcription. IFN‐I and IFN‐II can activate the IFI44L promoter through one of the two ISREs. IFN regulatory factor (IRF)‐1 can activate transcription of IFI44L by binding to one of the ISREs. Additionally, co‐transfection of the IFI44L promoter with an HIV‐1 infectious clone or HIV‐1 infection activated IFI44L promoter transcription, but did not upregulate IFI44L expression via ISREs. These findings will help to understand the interaction between IFI44L and HIV‐1, and aid in elucidation of the role of IFI44L in the antiviral innate immune response.
