Linearized Vpr, Tat, E1A, p300 and CtBP1 molecules as well as their mutual interaction domains. Vpr interacts with GR and several other other NRs through its LxxLL motif Positioned at amino acids 64 to sixty nine. Binding web pages of Vpr and p160-style HAT coactivators overlap with one another on p300. Since Vpr provides a LxxLL motif similar to p
