The POU homeodomain transcription factor Pit1 is required for pituitary development; here Pit1-occupied enhancers are shown to interact with the nuclear architecture components matrin-3 and Satb1, and this association is required for activation of Pit1-regulated enhancers and coding target genes. Long-read sequencing allows the assembly of antigen-gene arrays in Trypanosoma brucei and, coupled with deletion experiments, demonstrates that histone variants act as a molecular link between genome architecture, chromatin conformation and antigen variation. The functional role of peripheral localization in gene silencing is still unclear. You are using a browser version with limited support for CSS. Mol. Morgan, S. L. et al.
