- Extra Details:
- The positive transcription elongation factor b (P-TEFb) is identified as cdk9 paired with cyclin T1. The cyclin T1/cdk9 (PITALRE) complex phosphorylates the carboxy terminal domain of RNA Polymerase II in vitro and associate with HIV-1 generated Tat in HIV-1 infected T-cells. Tat stimulates human HIV-1 viral transcription elongation. This suggests that cyclin T1/cdk9 (PITALRE) is one of the HIV-1 required host cellular cofactors generated during T-cell activation. Cyclin T1/cdk9 (PITALRE) is shown to interact with Tat to restore Tat activation in HeLa nuclear extracts depleted of P-TEFb. The cdk9 (PITALRE) activity and cyclin T1 are essential for activation of transcription when tethered to the heterologous Rev response element RNA via the regulator of expression of virion Rev.
