In a developing yeast colony, cells go from homogeneous states to spatially organized, specialized metabolic states, and the new metabolic states depend on resources produced by the original state.

Relocation of Rab, Ras and Rho family GTPases to the surface of mitochondria enables efficient identification of their effectors, exchange factors and GAPs by proximity biotinylation.
RNAs enriched at cell protrusions are translated regardless of their location in the cytoplasm but are dynamically repressed in retracting protrusions and incorporated into heterogeneous RNA clusters.

Live-cell imaging shows that the contractile acto-myosin network on the nuclear envelope remnant positions chromosomes in early mitosis to ensure efficient and correct interactions between chromosomes and the mitotic spindle.

Hey together with LaminC continuously supervise nuclear organisation and differentiated enterocyte identity, a regulation that is lost upon ageing, resulting in loss of gut homeostasis.

The dynamic phosphorylation of autophagy component WIPI2B is critical to maintain autophagosome biogenesis in neurons, and ectopic expression of WIPI2B can restore rates of autophagosome biogenesis in aged neurons.
The autophagy protein ATG2A tethers membranes and transfers lipids between them, suggesting that autophagosome membranes grow upon the acquisition of lipids from the ER through the ATG2A bridge.
