To exert its key roles in the viral cycle, NCp7 interacts with several host proteins. Among them, the human NoL12 protein (hNoL12) was previously identified in genome wide screens as a potential partner of NCp7. hNoL12 is a highly conserved 25 kDa nucleolar RNA-binding protein implicated in the 5'end processing of ribosomal RNA in the nucleolus and thus in the assembly and maturation of ribosomes. In this work, we confirmed the NCp7/hNoL12 interaction in cells by Förster resonance energy transfer visualized by Fluorescence Lifetime Imaging Microscopy and co-immunoprecipitation. The interaction between NCp7 and hNoL12 was found to strongly depend on their both binding to RNA, as shown by the loss of interaction when the cell lysates were pretreated with RNase. Deletion mutants of hNoL12 were tested for their co-immunoprecipitation with NCp7, leading to the identification of the exonuclease domain of hNoL12 as the binding domain for NCp7. Finally, the interaction with hNoL12 was found to be specific of the mature NCp7 and to require NCp7 basic residues. IMPORTANCE HIV-1 mature nucleocapsid (NCp7) results from the maturation of the Gag precursor in the viral particle and is thus mostly abundant in the first phase of the infection which ends with the genomic viral DNA integration in the cell genome. Most if not all the nucleocapsid partners identified so far are not specific of the mature form. We described here the specific interaction in the nucleolus between NCp7 and the human nucleolar protein 12, a protein implicated in ribosomal RNA maturation and DNA damage response. This interaction takes place in the cell nucleolus, a subcellular compartment where NCp7 accumulates. The absence of binding between hNoL12 and Gag makes hNoL12 one of the few known specific cellular partners of NCp7."xsd:string |
