A genetic screen previously identified the N-terminal 91 amino acids of the eukaryotic initiation factor 3 subunit f (N91-eIF3f) as a potent inhibitor of HIV-1 replication. Overexpression of N91-eIF3f or full-length eIF3f reduced the level of HIV-1 mRNAs in the infected cell. Here we show that N91-eIF3f and eIF3f act by specifically blocking the 3′ end processing of the HIV-1 pre-mRNA both in vivo...
Cellular proteins are now appreciated as critically involved in all steps of the human immunodeficiency virus type 1 (HIV-1) life cycle, and disrupting host functions essential for virus replication may provide novel antiviral approaches. Selection from a human complementary DNA (cDNA) library for clones able to induce resistance to infection by recombinant HIV-1 genomes resulted in the identification...
