Linearized Vpr, Tat, E1A, p300 and CtBP1 molecules and their mutual conversation domains. Vpr interacts with GR and several other NRs as a result of its LxxLL motif Situated at amino acids sixty four to 69. Binding web pages of Vpr and p160-type HAT coactivators overlap with one another on p300. Due to the fact Vpr has a LxxLL motif comparable to p
