Abstract: Transcription of the HIV genome proceeds in distinct kinetic phases. Initially, short, multiply spliced mRNAs, which encode the viral regulatory proteins tat and rev, are expressed, whereas, late in infection production switches to full-length, unspliced transcripts that act both as the virion RNA and the mRNA for the gag-pol polyprotein. HIV-1 transactivator is reviewed in the following chapters: RNA interactions of the tat and rev proteins of HIV-1; the role of the TAR region and tat protein in HIV-directed gene expression; RNA-protein interactions required for regulation of HIV gene expression; cellular factors involved in regulating HIV gene expression; biochemical characterization of REV-RRE interaction; analysis of the structure of the HIV-1 tat protein; mechanisms of regulation of tat and rev; genome organization and regulation of HIV-1 expression; mechanism of function of the rex protein of HTLV-1; tat-mediated trans-activation as a presplicing event requiring a functional HIV-1 TATAA element; analysis of the TAT/TAR interaction in Xenopus oocytes; transcriptional regulation of HIV; functional topography of lentivirus tat proteins defined by domain switching; nucleolar targeting singles of HIV; characterization of the specific interaction between TAT and TAR RNA; and the exogenous trans-activation activity of HIV-1 tat.
