Striped expression of Dpp in Drosophila wing precursors leads to graded signalling activity that positions wing veins and, in parallel, promotes growth in a gradient-independent manner by supplying signalling activity above a threshold.

A recent report proposing that the dpp stripe (the main source of the protein dpp) is dispensable for Drosophila wing disc growth missed the critical role on growth due to imprecise spatial removal of dpp.

Intersectin counterparts in yeast recruit WASP and WIP to endocytic sites to establish a robust multivalent SH3 domain-PRM interaction network which gives actin assembly onset a switch-like behavior in vivo.

Necroptosis triggers organ-specific, age-associated deterioration of male reproductive system.

Sec17 (αSNAP) and Sec18 (NSF) are shown to act twice, to promote fusion per se and to recycle SNAREs after fusion.

Innovative approaches were used to identify the specific pharmacological properties of heterodimeric metabotropic glutamate receptors composed of mGlu2 and mGlu4 subunits, and reveal their existence in a neuronal cell line and in perforant path terminals.

Some RNAs in mammalian cells can help to silence the DNA they are transcribed from.

SUV39H1 histone methyltransferase directly binds chromosome associated RNA to promote constitutive heterochromatin formation.

A hierarchical model explains the self-organization of membrane microdoomaims.

Optogenetic control of Cdc42 activation during polarization of budding yeast demonstrates a cell cycle regulated switch between two distinct modes of positive feedback.
