Eviction notice: new insights into Rad51 removal from DNA during homologous recombination.
In this issue of Molecular Cell, Ward et al. (2010) identify two genes whose products act redundantly to clear Rad51 from DNA after successful strand invasion, thereby enabling the downstream events of homologous recombination to go smoothly.
متن کاملNitric oxide and cnidarian bleaching: an eviction notice mediates breakdown of a symbiosis.
Nitric oxide (NO) is a free radical implicated in numerous cell signaling, physiological and pathophysiological processes of eukaryotic cells. Here, we describe the production of NO as part of the cellular stress response of the symbiotic sea anemone Aiptasia pallida, which hosts dinoflagellates from the genus Symbiodinium. We show that exposure to elevated temperatures induces symbiotic anemon...
متن کاملEviction and the Children
So much has been achieved in the last fifty years in improving social conditions in this country that it is only right to state at once that the purpose of this article is not to be critical of what has been accomplished. Indeed, armed with some first-hand knowledge of the problem of evicted families, I am greatly impressed with the administration of the various measures designed to eliminate a...
متن کاملAsf1 mediates histone eviction and deposition during elongation by RNA polymerase II.
Histones are rapidly evicted and deposited during transcription by RNA polymerase (Pol) II, but a factor that mediates histone eviction in vivo has not yet been identified. Here, we show that the histone chaperone Asf1 associates with promoters and coding regions of transcriptionally active genes. Asf1 mediates histone H3, but not H2B, eviction and deposition during Pol II elongation, suggestin...
متن کاملEvidence for eviction and rapid deposition of histones upon transcriptional elongation by RNA polymerase II.
Biochemical experiments indicate that transcriptional elongation by RNA polymerase II (Pol II) is inhibited by nucleosomes and hence requires chromatin-modifying activities. Here, we examine the fate of histones upon passage of elongating Pol II in vivo. Histone density throughout the entire Saccharomyces cerevisiae GAL10 coding region is inversely correlated with Pol II association and transcr...
