The viral infectivity factor (Vif) protein of human immunodeficiency virus type 1 (HIV-1) is essential for viral replication in vivo. Packaging of Vif into viral particles is mediated by an interaction with viral genomic RNA and association with vira

The bifunctional reagent ethyl 4-azidobenzoylaminoacetimidate was used to crosslink specifically ribosomal protein S1 to 16-S RNA within 30-S subunits. The reagent was attached to isolated protein S1. The modified protein was reassociated with protei

HIV-1 reverse transcription is initiated from a tRNA(3)(Lys) molecule annealed to the viral RNA at the primer binding site (PBS), but the structure of the initiation complex of reverse transcription remains controversial. Here, we performed in situ s

Dimerization of bcd mRNA was shown to be important for the formation of ribonucleoprotein particles and their localization in Drosophila embryo. The cis-element responsible for dimerization is localized in a stem-loop domain (domain III) containing t

Reverse transcription of HIV-1 RNA is initiated from the 3' end of a tRNA 3 Lys molecule annealed to the primer binding site (PBS). An additional interaction between the anticodon loop of tRNA 3 Lys and a viral A-rich loopis required for efficient in

The loss of the fragile X mental retardation protein (FMRP) is responsible for the most common cause of inherited mental retardation called the fragile X syndrome. FMRP is suspected to participate in the synaptic plasticity of neurons by acting on po

HIV-1 utilizes cellular tRNA(3)(Lys) to prime the initiation of reverse transcription. The selective incorporation of cytoplasmic tRNA(3)(Lys) into HIV-1 particles was recently shown to involve the lysyl-tRNA synthetase, and hence, the encapsidated t

In addition to its role in tRNA aminoacylation, Escherichia coli threonyl-tRNA synthetase is a regulatory protein which binds a site, called the operator, located in the leader of its own mRNA and inhibits translational initiation by competing with r

Human immunodeficiency virus (HIV) genomic RNA is packaged into virions as a dimer. The first step of dimerization is the formation of a kissing-loop complex at the so-called dimerization initiation site (DIS). We found an unexpected and fortuitous r

A cyclic molecule constituted by (i) a hexameric PNA moiety complementary to six among the nine residues of the dimerization initiation site loop of HIV-1 and (ii) a spacer tethering the N- to the C-extremities of the PNA, has been elaborated to inhi
