Characterization of U2AF26, a Paralog of the Splicing Factor U2AF35
… is composed of a large subunit, U2AF65, and a small subunit, U2AF35. U2AF65 recognizes the pyrimidine tract and U2AF35 binds to the AG dinucleotide, both of which are specific 3' splice site sequence motifs. In the present work U2AF26, a paralog of the conventional U2AF35, has been studied. …

Enzymatic Disassembly of Promoter Bound 7SK snRNP Drives Transcription Elongation of HIV and Cellular Genes
… inactive form, reversibly bound to the 7SK small nuclear ribonucleoprotein (snRNP). In the absence of stimuli, the 7SK snRNP resides in both the nucleoplasm and promoter regions. However, an understanding of how TF’s capture P-TEFb from the 7SK snRNP at the promoter and the mechanism and …
