Inside the acidic vacuole, expression, DNA binding and DNA binding affinity of the Salmonella regulator SsrB is stimulated by acid pH.

The signaling lipid PI(3,5)P₂ supports the formation of the myelin sheath, by regulating trafficking of myelin building blocks within oligodendrocytes and communication between oligodendrocytes and neuronal axons.

The polarity protein crumbs controls apical secretion and the architecture of the apical domain by modulating PI(4,5)P₂ levels and the organization of apical Rab6-, Rab11-, and Rab30-dependent trafficking.

Polo kinase recruitment by the protein Spd-2 to the pericentriolar scaffold is a key element of the positive feedback loop which drives the expansion of the mitotic centrosomes in flies.

A genetic screen and live cell imaging show that a newly identified coiled-coil protein called SAS-7 is the earliest acting factor in centriole assembly yet identified in the roundworm Caenorhabditis elegans.

Many vertebrates are able to synthesize a sunscreen compound de novo and the pathway involved can be used for heterologous production of the compound in yeast.

The lysosomal ion channel TPC2 emerges as an example of an ion channel in which ion selectivity is not fixed but rather agonist-selective.

In vivo evidence is provided indicating that Flv2/Flv4, together with Flv1/Flv3, mediate O₂ photoreduction downstream of PSI in a highly coordinated manner.
