Repair at the nuclear periphery
T elomere association with nuclear pores is critical not only for transcriptional silencing but also for effi cient repair of double-stranded breaks in the subtelomeric region of budding yeast chromosomes, according to Therizols et al. (page 189). As in many organisms, yeast telomeres localize to the nuclear periphery. To determine whether nuclear pore proteins are involved in telomere tetherin...
متن کاملConserved gene order at the nuclear periphery in Drosophila.
Whether higher-order chromatin organization is related to genome stability over evolutionary time remains elusive. We find that regions of conserved gene order across the genus Drosophila are larger if they harbor genes bound by B-type lamin (Lam) and Suppressor of Under-Replication (SUUR), two proteins located at the nuclear periphery. Low recombination rates and coexpression of genes in regio...
متن کاملRepairing subtelomeric DSBs at the nuclear periphery.
Nuclear organization creates microenvironments favoring distinct nuclear functions. In budding yeast, silent chromatin regions such as telomeres are clustered at the nuclear periphery, creating zones of transcriptional repression. Recently, in the Journal of Cell Biology, Therizols et al. report that "telomere tethering at the nuclear periphery is essential for DNA double strand break repair in...
متن کاملThe nuclear periphery
In recent years, definitions of the nuclear periphery have become increasingly blurred with the realization that nuclear envelope (NE) and nuclear pore complex (NPC) components interact with and influence the behavior of both nuclear and cytoplasmic structures. The Minisymposium on the Nuclear Periphery reflected this evolving outlook by bringing together an eclectic group of researchers workin...
متن کاملStrategies to regulate transcription factor–mediated gene positioning and interchromosomal clustering at the nuclear periphery
In budding yeast, targeting of active genes to the nuclear pore complex (NPC) and interchromosomal clustering is mediated by transcription factor (TF) binding sites in the gene promoters. For example, the binding sites for the TFs Put3, Ste12, and Gcn4 are necessary and sufficient to promote positioning at the nuclear periphery and interchromosomal clustering. However, in all three cases, gene ...
