Asf1 is a conserved H3/H4 histone chaperone with multiple functions in chromatin modulation. Using budding yeast as a model, we identify new pathways of Asf1 function, and expand current knowledge regarding the known roles of Asf1. First, we uncover novel genetic interactions between ASF1 and...

Chromatin structure is important aspect of transcriptional regulation. Replication-coupled (RC) nucleosome assembly is the process of depositing newly synthesized H3-H4 onto nascent DNA behind the replication fork, mediated by the histone chaperones Asf1, CAF-1, and Rtt106. The experiments...

RNA polymerase III (RNAPIII) pre-initiation complexes at tRNA genes naturally cause replication fork pausing in the yeast Saccharomyces cerevisiae, and interference with replication is known to have deleterious effects on genome stability. It follows that repression of tRNA gene transcription...

Metabolic enzymes are active in both the nucleus and cytoplasm. While metabolism in cytoplasm is widely acknowledged for energy production, nuclear-localized metabolic enzymes are thought to modulate availability of metabolites used in epigenetics. A thorough investigation of this regulatory...
