Human Immunodeficiency Virus Type 1 hnRNP A/B-Dependent Exonic Splicing Silencer ESSV Antagonizes Binding of U2AF65 to Viral Polypyrimidine Tracts

11 Nov 2003

Abstract excerpt

Human immunodeficiency virus type 1 (HIV-1) exonic splicing silencers (ESSs) inhibit production of certain spliced viral RNAs by repressing alternative splicing of the viral precursor RNA. Several HIV-1 ESSs interfere with spliceosome assembly by binding cellular hnRNP A/B proteins. Here, we have further characterized the mechanism of splicing repression using a representative HIV-1 hnRNP A/B-dependent ESS, ESSV,...
