Structural basis for the inhibition of cGAS by nucleosomes.
(AMER ASSOC ADVANCEMENT SCIENCE, 2020-10-23)
The cyclic guanosine monophosphate-adenosine monophosphate synthase (cGAS) senses invasion of pathogenic DNA and stimulates inflammatory signaling, autophagy, and apoptosis. Organization of host DNA into nucleosomes was ...
The role of the SWI/SNF chromatin remodelling complex in the response to DNA double strand breaks.
(ELSEVIER, 2020-09-01)
Mammalian cells possess multiple closely related SWI/SNF chromatin remodelling complexes. These complexes have been implicated in the cellular response to DNA double strand breaks (DSBs). Evidence suggests that SWI/SNF ...
Structure of a nucleosome-bound MuvB transcription factor complex reveals DNA remodelling.
(NATURE PORTFOLIO, 2022-08-29)
Genes encoding the core cell cycle machinery are transcriptionally regulated by the MuvB family of protein complexes in a cell cycle-specific manner. Complexes of MuvB with the transcription factors B-MYB and FOXM1 activate ...
TOPBP1 recruits TOP2A to ultra-fine anaphase bridges to aid in their resolution.
(NATURE PUBLISHING GROUP, 2015-03-12)
During mitosis, sister chromatids must be faithfully segregated to ensure that daughter cells receive one copy of each chromosome. However, following replication they often remain entangled. Topoisomerase IIα (TOP2A) has ...
The mechanism of replication stalling and recovery within repetitive DNA.
(NATURE PORTFOLIO, 2022-07-19)
Accurate chromosomal DNA replication is essential to maintain genomic stability. Genetic evidence suggests that certain repetitive sequences impair replication, yet the underlying mechanism is poorly defined. Replication ...
