The specific hydrolysis of HIV-1 TAR RNA element with the anti-TAR hammerhead ribozyme: structural and functional implications.


The main transcriptional regulator of the human immunodeficiency virus is the Tat protein, which recognises and binds to a fragment RNA at the 5' end of viral mRNA, named transactivation response element (TAR) RNA. Extensive mutagenesis studies have shown that a region of TAR RNA important for Tat binding involves a set of nucleotides surrounding a… (More)
