Abstract
In accordance with the present invention, isolated nucleic acid encoding a host cell protein that regulates Tat transactivation has been discovered. The protein is the first discovered constituent of the TAK/TEFb complex which associates with the HIV Tat, via divalent cation metals, and is necessary for the binding of Tat to TAR RNA. This protein, cyclin T1, is an 87 kDa cyclin partner for the PITALRE kinase. It is further discovered that Tat must interact with TAK in order to bind to TAR RNA with affinity and with the appropriate sequence specificity that is observed in vivo. In accordance with another aspect of the invention, formulations useful for modulation of Tat transactivation have been developed. In addition, assays have been developed for the identification of compounds useful to modulate the above-described processes.
