Serine ADP-ribosylation marks nucleosomes for ALC1-dependent chromatin remodeling

ADP-核糖基化

染色质重塑

Serine ADP-ribosylation (ADPr) is a DNA damage-induced post-translational modification catalyzed by the PARP1/2:HPF1 complex. As the list of PARP1/2:HPF1 substrates continues to expand, there is a nee

The histone variant H2A.Z in yeast is almost exclusively incorporated into the +1 nucleosome in the direction of transcription

组蛋白变体定位

染色质重塑

To investigate the incorporation dynamics of histone variant H2A.Z, we determined its genomic localization at single nucleosome resolution, as well as the localization of its chromatin remodelers Swr1

RNA测序

In eukaryotes, DNA is associated with histones to form nucleosomes, the basic component of the chromatin. This structure presents a physical barrier for nuclear proteins to access DNA and, therefore,

The chromatin remodelling factor ATRX suppresses R-loops in transcribed telomeric repeats

R-loop调控

染色质重塑

ATRX is a chromatin remodelling factor found at a wide range of tandemly repeated sequences including telomeres (TTAGGG)n. Acquired mutations in ATRX are found in nearly all tumours which maintain the
