Diverse mutants of HIV RRE IIB recognize wild-type Rev ARM or Rev ARM R35G-N40V.

Abstract excerpt

The binding of human immunodeficiency virus Rev protein via its arginine-rich motif (ARM) to an internal loop in the Rev-response element region IIB (RRE IIB) is necessary for viral replication. Many variant RNAs and ARMs that bind Rev and RRE IIB have been found. Despite the essential role of Rev asparagine 40 in recognition, the Rev ARM double-mutant R35G-N40V functions well in a Rev-RRE IIB reporter assay,...
