In accordance with the present invention, a host cell protein has been discovered which regulates Tat transactivation. The protein is the first discovered constituent of the TAK/TEFb complex which associates with HIV Tat, via divalent cation metals, and is necessary for the binding of Tat to TAR RNA. This protein, cyclin T1, is an 87kDa 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.

La présente invention concerne la découverte d'une protéine de cellule hôte régulant la transactivation de Tat. La protéine est le premier constituant du complexe TAK/TEFb que l'on ait découvert qui s'associe avec la protéine Tat du VIH, via des métaux à cations divalents, et elle est nécessaire à la liaison de la protéine Tat avec l'ARN TAR. Cette protéine, la cycline T1, est un partenaire de la cycline de 87 kDa pour la kinase PITALRE. On a également découvert que la protéine Tat doit interagir avec TAK pour se lier avec l'ARN TAR avec affinité et avec la spécificité de séquence appropriée observée in vivo. Selon un autre aspect de l'invention, des formulations utiles pour la modulation de la transactivation de la protéine Tat ont été mises au point. En outre, des analyses ont été mises au point en vue de l'identification de composés utiles pour la modulation des processus précités.
