General description
Protein VPRBP (EC 2.7.11.1; UniProt Q9Y4B6; also known as DDB1- and CUL4-associated factor 1, HIV-1 Vpr-binding protein, Serine/threonine-protein kinase VPRBP, Vpr-interacting protein, VprBP) is encoded by the VPRBP (also known as DCAF1, KIAA0800, RIP) gene (Gene ID 9730) in human. VprBP/DCAF1 acts as an adaptor molecule that mediates substrates recruitment for both the RING-type CRL4 (Cul4-Roc1-DDB1) and HECT-type EDD/UBR5 E3 ubiquitin ligase complexes. CRL4 substrates known to be recruited by VprBP include Merlin, Mcm10, UNG2, SMUG1, RORαme1. Known EDD/UBR5 substrates recruited by VprBP include Katanin and TERT. VprBP is involved in a variety of normal cellular processes, including proliferation, DNA replication, cell cycle progression, telomere maintenance, and DNA damage responses. As indicated by its name, VprBP is also a well known target utilized by the Vpr and Vpx accessory factors of primate lentiviruses to highjack the host CRL4VprBP E3 ligase function.
