An unbiased genome-wide human forward genetic screen identifies the vacuolar ATPase complex and assembly factors as regulators of HIF stability through their actions on intracellular iron metabolism.
A posttranslational regulatory mechanism for a Ras family small GTPase could open up new directions to understand and control the Ras family of proteins that are important for physiology and diseases.
p27Kip1 directly controls invadopodia turnover by promoting the interaction of PAK1 with Cortactin, which induces Cortactin phosphorylation, invadopodia disassembly and facilitates invasion through extracellular matrix.

Functionalized protein binders, anchored to specific regions along the cell cortex, provide a novel approach to directly modify protein localization and dispersal in vivo.
The scaffold Bem1 increases the rate of GEF-mediated Cdc42 activation, while also increasing the rate and extent of GEF phosphorylation by PAK, which attenuates further scaffold stimulation.

Kinesin-4 KIF21B combines a processive motor activity with two non-motor microtubule-binding domains and an autoregulatory region to induce pausing of microtubule plus ends.

Although genetically and biochemically linked, the plant immune and growth receptors FLS2 and BRI1 form dispersed receptor clusters within the plasma membrane that are spatiotemporally separated.
Cellular and tissue level analysis reveals how different cell behaviors involving dynamics of the basal domain cooperate in space and time to shape an epithelial organ.
