Epigenetic Regulation of Polymerase II Transcription Initiation in Trypanosoma cruzi: Modulation of Nucleosome Abundance, Histone Modification, and Polymerase Occupancy by O-Linked Thymine DNA Glucosylation

Abstract excerpt

Very little is understood regarding how transcription is initiated/regulated in the early-diverging eukaryote Trypanosoma cruzi. Unusually for a eukaryote, genes transcribed by RNA polymerase (Pol) II in T. cruzi are arranged in polycistronic transcription units (PTUs). On the basis of this gene organization, it was previously thought that trypanosomes rely solely on posttranscriptional processes to regulate gene...
