Epigenetic restriction of herpes simplex virus occurs in a biphasic manner, in which ATRX maintains viral heterochromatin after an initial phase of chromatin deposition.
ATR protects stem cell genomes by activating a transcriptional response mediated by totipotency genes, conferring trophoblast differentiation potential, the derepression of which in somatic cells might favour cancer features emergence.
ATM plays an important role in maintaining the fidelity of DNA repair through the regulation of ARP8 phosphorylation to prevent the chromosome abnormality.
During meiosis, budding yeast use a checkpoint involving the protein Mec1 to prevent the formation of double-strand breaks in DNA that has not completed replication.
Genetic and biochemical analysis reveal a variant in HSF2BP causing POI and C19ORF57/BRME1 as an interactor and stabilizer of HSF2BP by forming a complex with BRCA2, RAD51, RPA and PALB2.
Genetic analyses using the fruit fly illustrate how neuronal system couples germline stem cell increase to an external cue, which is mating, through stem cell niche signaling.
