The mammalian radiation has corresponded with rapid changes in noncoding regions of the genome, but we lack a comprehensive understanding of regulatory evolution in mammals. Here, we track the evolution of promoters and enhancers active in liver across 20 mammalian species from six diverse orders by profiling genomic enrichment of H3K27 acetylation and H3K4(More)
The replicase of E. coli, DNA polymerase III holoenzyme, is tightly fastened to DNA by its ring-shaped beta sliding clamp. However, despite being clamped to DNA, the polymerase must rapidly cycle on and off DNA to synthesize thousands of Okazaki fragments on the lagging strand. This study shows that DNA polymerase III holoenzyme cycles from one DNA to(More)
Type 1 serine/threonine protein phosphatases (PP1) are important regulators of many cellular and developmental processes, including glycogen metabolism, muscle contraction, and the cell cycle [1] [2] [3] [4] [5]. Drosophila and humans both have multiple genes encoding PP1 isoforms [3] [6] [7]; each has one beta and several alpha isoform genes (alpha(1),(More)
