    AFF4 binding to Tat-P-TEFb indirectly stimulates TAR recognition of super elongation complexes at the HIV promoter

    Ursula Schulze-Gahmen et al.
    AFF4 increases the combined selectivity of HIV Tat and TAR for super elongation complexes 330-fold over P-TEFb alone.

    HIV Tat controls RNA Polymerase II and the epigenetic landscape to transcriptionally reprogram target immune cells

    Jonathan E Reeder et al.
    Tat uses unexpected regulatory mechanisms to reprogram target immune cells to promote viral replication and rewire pathways beneficial for HIV.

    Skd3 (human ClpB) is a potent mitochondrial protein disaggregase that is inactivated by 3-methylglutaconic aciduria-linked mutations

    Ryan R Cupo, James Shorter
    Skd3 (human ClpB) is a potent ATP-dependent mitochondrial protein disaggregase that is activated by the rhomboid protease, PARL, and inactivated by MGCA7-linked mutations.

    Insights into HIV-1 proviral transcription from integrative structure and dynamics of the Tat:AFF4:P-TEFb:TAR complex

    Ursula Schulze-Gahmen et al.
    The crystal structure of the trans-activation response region (TAR) bound to HIV-1 Tat and an elongation factor, together with HDX, SHAPE, SAXS, and integrative modeling, shows how TAR binds this complex in two ways.
