Dynamics of DNA damage response proteins at DNA breaks: a focus on protein modifications.

abstract：:Cascades of zygotic gene expression pattern the anterior-posterior (AP) and dorsal-ventral (DV) axes of the early Drosophila embryo. Here, we used the global run-on sequencing assay (GRO-seq) to map the genome-wide RNA polymerase distribution during early Drosophila embryogenesis, thus providing insights into how gene...

abstract：:H4K20 methylation is a broad chromatin modification that has been linked with diverse epigenetic functions. Several enzymes target H4K20 methylation, consistent with distinct mono-, di-, and trimethylation states controlling different biological outputs. To analyze the roles of H4K20 methylation states, we generated c...
