Binding of hnRNP L to the Pre-mRNA Processing Enhancer of the Herpes Simplex Virus Thymidine Kinase Gene Enhances both Polyadenylation and Nucleocytoplasmic Export of Intronless mRNAs

Abstract excerpt

Liu and Mertz (Genes Dev. 9:1766-1780, 1995) previously identified a 119-nt pre-mRNA processing enhancer (PPE) element within the herpes simplex virus type 1 thymidine kinase gene that enables intron-independent gene expression in higher eukaryotes by binding heterogeneous nuclear ribonucleoprotein L (hnRNP L). Here, we identify a 49-nt subelement within this PPE that enhanced stability, polyadenylation, and...
