Abstract
The mechanisms involved in the posttranscriptional control of the replicative cycle of the human immunodeficiency virus (HIV), specifically the molecular events which allow the interaction between the viral genomic RNA (gRNA) and the cellular machinery for the transport, translation, or intracellular packaging, have not been yet elucidated. In this chapter, we describe the in situ hybridization-proximity ligation assay (ISH-PLA) to characterize interactions between the genomic RNA (gRNA) of HIV-1 and viral proteins or host proteins involved in nuclear export and translation initiation. We also present data that validate the ISH-PLA as a simple and useful tool to study HIV-1 gRNA-protein interactions within cells.
