The HIV-1 Rev response element
The HIV-1 Rev response element (RRE) is a ~350 nucleotide, highly structured, cis-acting RNA element essential for viral replication. It is located in the env coding region of the viral genome and is extremely well conserved across different HIV-1 isolates. It is present on all partially spliced and unspliced viral mRNA transcripts, and serves as an RNA framework onto which multiple molecules o...
متن کاملReal-time kinetics of HIV-1 Rev-Rev response element interactions. Definition of minimal binding sites on RNA and protein and stoichiometric analysis.
The kinetics of interaction between the human immunodeficiency virus-1 Rev protein and its RNA target, Rev response element (RRE) RNA was determined in vitro using a biosensor technique. Our results showed that the primary Rev binding site is a core stem-loop RNA molecule of 30 nucleotides that bound Rev at a 1:1 ratio, whereas the 244-nucleotide full-length RRE bound four Rev monomers. At high...
متن کاملRNA-directed remodeling of the HIV-1 protein Rev orchestrates assembly of the Rev–Rev response element complex
The HIV-1 protein Rev controls a critical step in viral replication by mediating the nuclear export of unspliced and singly-spliced viral mRNAs. Multiple Rev subunits assemble on the Rev Response Element (RRE), a structured region present in these RNAs, and direct their export through the Crm1 pathway. Rev-RRE assembly occurs via several Rev oligomerization and RNA-binding steps, but how these ...
متن کاملSelection of Structure-Specific Inhibitors of the HIV Rev-Rev Response Element Complex
We devised a single-step selection method to identify short sequences within the folded Rev response element (RRE) of the human immunodeficiency virus (HIV) RNA genome that are proximal and able to bind short oligonucleotides. The method employed a library of partially randomized tethered oligonucleotide probes (TOPs) complementary to all regions of the RRE and an RNase H cleavage assay which i...
متن کاملHIV Rev Assembly on the Rev Response Element (RRE): A Structural Perspective
HIV-1 Rev is an ~13 kD accessory protein expressed during the early stage of virus replication. After translation, Rev enters the nucleus and binds the Rev response element (RRE), a ~350 nucleotide, highly structured element embedded in the env gene in unspliced and singly spliced viral RNA transcripts. Rev-RNA assemblies subsequently recruit Crm1 and other cellular proteins to form larger comp...
