Abstract
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.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
