Simulations of molecular dynamics suggest how the binding of the β-grasp domain of SUMO1 induces conformational and dynamic effects to activate SENP1.

Inhibition of the catalytic activity of the Zap70 kinase reveals that discrete TCR-regulated events control the remodelling of the actin cytoskeleton when the cytotoxic T cell interacts with its target.

Improved technology for counting proteins captures myosin 10 dynamics throughout the filopodial lifecycle, defines requirements for initiating filopodia, and reveals a crowded filopodial tip where motors frequently exceed available actin.

Uso1 critically regulating traffic in the ER/Golgi interface is a coiled-coil protein traditionally regarded as a tether, but a forward genetic screen revealed that its essential role appears to involve its ability to interact with SNAREs.
