Splicing efficiency of human immunodeficiency virus type 1 tat RNA is determined by both a suboptimal 3' splice site and a 10 nucleotide exon splicing silencer element located within tat exon 2

Abstract excerpt

We have previously demonstrated that an exon splicing silencer (ESS) is present within human immunodeficiency virus type 1 (HIV-1)tat exon 2. This 20 nucleotide (nt) RNA element acts selectively to inhibit splicing at the upstream 3'splice site (3'ss #3) flanking this exon. In this report, we have used in vitro splicing of mutated RNA substrates to determine the sequences necessary and sufficient for the activity...
