Coordination between crossover designation and synaptonemal complex disassembly is executed via a conserved MAP kinase pathway and is critical for accurate chromosome segregation during meiosis.
Selective APC/C-mediated proteolysis of cyclin B drives progression through the metaphase-anaphase transition whilst wide-spread waves of dephosphorylation co-ordinate the subsequent events of mitotic exit.
The TRAIP ubiquitin ligase is required during mitosis to disassemble the replisome at sites of incomplete DNA replication, and activate the mitotic DNA repair pathway, thus preserving genome integrity.
The condensin I subunit Cap-G is expressed in post-mitotic neurons and its removal, especially from less mature neurons, results in gene expression changes, reduced survival and behavioural defects in Drosophila.
The scaling of spindle elongation velocity with cell size is regulated by the amounts of Kinesin-6 molecules and the number of binding sites for the motor to the mitotic spindle.
Direct live-cell imaging of human cells, combined with RNA-seq, qPCR and in vitro reconstitution essays, reveal that mitotic progression, arrest, exit or death is independent of de novo transcription.
A regulatory circuit that localizes to the synaptonemal complex, a liquid crystalline compartment between chromosomes, ensures crossing-over while limiting the number of crossovers between homologous chromosomes during meiosis.
Analysis of a spermiogenesis protein reveals a new chromatin requirement for synchrony between maternal DNA packaged in the egg and sperm-packaged paternal DNA in the first embryonic mitosis in Drosophila melanogaster.
