UHRF1 Suppresses HIV-1 Transcription and Promotes HIV-1 Latency by Competing with p-TEFb for Ubiquitination-Proteasomal Degradation of Tat

31 Aug 2021

Abstract excerpt

HIV-1 latency is systematically modulated by host factors and viral proteins. In our work, we identified a critical role of host factor ubiquitin-like with PHD and RING finger domain 1 (UHRF1) in HIV-1 latency via the modulation of the viral protein Tat stability. By disrupting the Tat/cyclin T1/CDK9 complex, UHRF1 promotes the suppression of HIV-1 transcription and maintenance of HIV-1 latency. Our findings...
