To keep itself in check, Plk4 encourages its own removal.

People & Ideas

The intrepid Yamada has made many discoveries while mapping out cell adhesion and motility.



Plk4 phosphorylates itself in trans to prevent accumulation and self-limit kinase activity, which may be important for regulating centriole duplication.

Keeping Wee1B in the nucleus is important to maintain meiotic arrest, but its timely export is also required for meiosis to resume.


Cdk activity can differentially regulate the number of active replication factories, replication rates, and the rate of progression through the timing program during S phase.

Soluble ERAD substrates strictly require the Hrd1 E3 ligase for degradation compared with membrane-anchored peptides that may also use other E3 ligases.

Two peripheral GRASP membrane proteins work together to keep the Golgi from falling apart.

FYCO1 recognition of LC3 on autophagosomes facilitates microtubule-mediated cytosolic transport of this degradative organelle.

RhoA is activated from internalized Nogo-A to promote growth cone collapse and inhibit neurite outgrowth.

Analysis of the relationship between actin network velocity and traction forces at the substrate shows that force transmission mechanisms vary with distinct regions of the cell.
