For example, VprBP/DCAF1 targets NF2 to the E3 ubiquitin-ligase complex for ubiquitination and subsequent proteasome-dependent degradation. In case of infection by HIV-1 virus, it is recruited by HIV-1 Vpr in order to hijack the CUL4A-RBX1-DDB1 function leading to arrest the cell cycle in G2 phase, and also to protect the viral protein from proteasomal degradation by another E3 ubiquitin ligase. In case of infection by HIV-2 virus, it is recruited by HIV-2 Vpx in order to hijack the CUL4A-RBX1-DDB1 function leading to enhanced efficiency of macrophage infection and promotion of the replication of cognate primate lentiviruses in cells of monocyte/macrophage lineage. Associated with chromatin in a DDB1-independent and cell cycle-dependent manner, VprBP/DCAF1 is recruited to chromatin as DNA is being replicated and is released from chromatin before mitosis.<ref>PMID:17314515</ref> <ref>PMID:17620334</ref> <ref>PMID:17626091</ref> <ref>PMID:17630831</ref> <ref>PMID:17609381</ref> <ref>PMID:17559673</ref> <ref>PMID:18524771</ref> <ref>PMID:18606781</ref> <ref>PMID:18332868</ref> <ref>PMID:18464893</ref> <ref>PMID:19264781</ref> <ref>PMID:19923175</ref> <ref>PMID:23063525</ref>	+	[https://www.uniprot.org/uniprot/MERL_MOUSE MERL_MOUSE] Probable regulator of the Hippo/SWH (Sav/Wts/Hpo) signaling pathway, a signaling pathway that plays a pivotal role in tumor suppression by restricting proliferation and promoting apoptosis.

		+	== Publication Abstract from PubMed ==
		+	The tumor suppressor gene Nf2 product, Merlin, plays vital roles in controlling proper development of organ sizes by specifically binding to a large number of target proteins localized both in cytoplasm and nuclei. The FERM domain of Merlin is chiefly responsible for its binding to target proteins, although the molecular basis governing these interactions are poorly understood due to lack of structural information. Here we report the crystal structure of the Merlin FERM domain in complex with its binding domain derived from the E3 ubiquitin ligase substrate adaptor DCAF1 (also known as VPRBP). Unlike target binding modes found in ERM proteins, the Merlin-FERM binding domain of DCAF1 folds as a beta-hairpin and binds to the alpha1/beta5-groove of the F3 lobe of Merlin-FERM via extensive hydrophobic interactions. In addition to providing the first structural glimpse of a Merlin-FERM/target complex, the structure of the Merlin/DCAF1 complex is likely to be valuable for understanding Merlin's interactions with its binding partners other than DCAF1.
