Physical interaction with Spo11 mediates the localisation of Mre11 to chromatin in meiosis and promotes its nuclease activity
Ontology highlight
ABSTRACT: Meiotic recombination is of central importance for the proper segregation of homologous chromosomes and is initiated by DNA double-strand breaks (DSB) that depend on Spo11 and Mre11. Calibrated chromatin immunoprecipitation (ChIP) for Mre11 shows that Spo11 promotes Mre11 recruitment to chromatin, independent of DSB formation. A C-terminal deletion mutant deficient in Spo11 interaction severely reduces the association of Mre11 with meiotic chromatin. Consistent with the reduction of Mre11 foci in this mutant, it strongly impedes DSB formation, leading to spore death.
