However, the molecular mechanisms underlying their functions remain largely incomplete. In this study, we report that the SLFN family member SLFN14 has potent anti\u2013HIV-1 activity. Specifically, SLFN14 binds to the positive transcription elongation factor b (P-TEFb), thereby preventing HIV-1 Tat-mediated recruitment of P-TEFb to the HIV-1 promoter and causing an arrest of viral transcription. Furthermore, this P-TEFb\u2013targeted inhibiting activity also allows SLFN14 to regulate the transcription of a subset of cellular genes. Thus, our data identify SLFN14 as an inhibitor of the important transcription elongation factor P-TEFb complex, which unveils the crucial role of SLFN14 in both cellular antiviral defense and other important cellular processes that rely on the function of this complex.\n
