Selective optimization of the Rev-binding element of HIV-1.

RNA molecules that can bind to the Rev protein of HIV-1 have been isolated from random sequence nucleic acid pools based on a minimal Rev-binding element (RBE) found within the Rev Responsive Element (RRE). While the selected sequences are related to the wild-type element, they also contain substitutions that allow them to bind Rev up to 10-fold better in vitro. A hypothesized homopurine pairin...

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...

Implications of the HIV-1 Rev dimer structure at 3.2 A resolution for multimeric binding to the Rev response element.

HIV-1 Rev is a small regulatory protein that mediates the nuclear export of viral mRNAs, an essential step in the HIV replication cycle. In this process Rev oligomerizes in association with a highly structured RNA motif, the Rev response element. Crystallographic studies of Rev have been hampered by the protein's tendency to aggregate, but Rev has now been found to form a stable soluble equimol...

A nucleolar localizing Rev binding element inhibits HIV replication

The Rev protein of the human immunodeficiency virus (HIV) facilitates the nuclear export of intron containing viral mRNAs allowing formation of infectious virions. Rev traffics through the nucleolus and shuttles between the nucleus and cytoplasm. Rev multimerization and interaction with the export protein CRM1 takes place in the nucleolus. To test the importance of Rev nucleolar trafficking in ...

RNA-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 ...
