Nuclear Factor 90(NF90) targeted to TAR RNA inhibits transcriptional activation of HIV-1

Abstract
Examination of host cell-based inhibitors of HIV-1 transcription may be important for attenuating viral replication. We describe properties of a cellular double-stranded RNA binding protein with intrinsic affinity for HIV-1 TAR RNA that interferes with Tat/TAR interaction and inhibits viral gene expression.
