'''VPRBP''' (VPR-binding protein) is a HIV-1 WD40 protein is essential for DNA replication and embryonic development<ref>PMID:18606781</ref>.  VPRBP has intrinsic kinase activity and is capable of phosphorylating histone H2A.  Recruitment of VPRBP by VPR is essential for HIV-1 VPR activity of initiating the host cell response cycle arresting its G(2) phase following mitosis<ref>PMID:17314515</ref>.
'''VprBP''' (VPR-binding protein) is a HIV-1 WD40 protein is essential for DNA replication and embryonic development<ref>PMID:18606781</ref>.  VprBP has intrinsic kinase activity and is capable of phosphorylating histone H2A.  Recruitment of VprBP by Vpr is essential for HIV-1 VPR activity of initiating the host cell response cycle arresting its G(2) phase following mitosis<ref>PMID:17314515</ref>. VprBP interacts with merlin which is then recruited to the E3 ligase complex resulting in its polyubiquitination and consequently its proteasome-mediated degradation<ref>PMID:18332868</ref>.
