Identification of a novel human zinc finger protein that specifically interacts with the activation domain of lentiviral Tat proteins.

Abstract

Transcriptional activation of HIV-1 gene expression by the viral Tat protein requires the interaction of a cellular cofactor with the Tat activation domain. This domain has been shown to consist of the cysteine-rich and core motifs of HIV-1 Tat and is functionally conserved in the distantly related Tat proteins of HIV-2 and EIAV. Using the yeast two-hybrid… (More)
