Linearized Vpr, Tat, E1A, p300 and CtBP1 molecules as well as their mutual conversation domains. Vpr interacts with GR and several other other NRs as a result of its LxxLL motif Found at amino acids 64 to sixty nine. Binding websites of Vpr and p160-style HAT coactivators overlap with each other on p300. Since Vpr contains a LxxLL motif much like p
