Background: Human immunodeficiency virus type 1 (HIV-1) Nef-encoded protein plays key functions at almost all stages of the viral life cycle, but its role in translation is largely unknown. Methods: To determine the effect of Nef on translation we used an in vitro translation assay. The detection of Nef/RPS10 complexes and the presence of 18S rRNA and tRNAs in the complexes were performed by coimmunoprecipitation and RT-PCR assay. Results: We observed that the HIV-1 Nef protein specifically impaired translation in vitro. We observed the interaction of Nef with RPS10 by coimmunoprecipitation assay. In addition 18S rRNA and tRNAs were present in the Nef/RPS10 complexes. Conclusions: Our results are consistent with a model in which the Nef protein by binding to two components of the 40S small ribosomal subunit, RPS10 and 18S rRNA, and to a lesser extent to tRNAs, could lead to decreased protein synthesis.
