Microtubule-based memory helps orient dividing brain stem cells.

People & Ideas

Vernos uses cutting-edge microscopy to track spindle assembly in Xenopus eggs.




WEE1 and CHK1 jointly regulate Cdk activity to prevent DNA damage during replication.


ATR recognizes critically short telomeres as fragile sites and protects them from chromosomal fusions.

Chromatin entanglements undergo specific protein-mediated compaction to fold into mitotic chromosomes.

An automated, quantitative 4D image analysis method is used to track kinetochore dynamics in metaphase cells.

Kinetochore protein CENP-I is regulated by SUMO protease SENP6 and RNF4, a ubiquitin ligase which targets polysumoylated proteins for degradation during mitosis.

The orientation of stem cell divisions is maintained beyond one cell cycle thanks to microtubule polymerization and apical centrosome positioning.

Additional factors combine with the core Hrd1 complex in a modular fashion, enabling it to recognize a variety of substrates.

Defective attenuation of BMP signaling causes synapses to overgrow in Drosophila Ema mutants due to impaired endosomal maturation.

Transcription factor Twist promotes cell junctions to link individual cells into a contractile network responsible for the apical constriction pulses during epithelial morphogenesis.
