Nedd4 Branches Out
The branching of dendrites and axons is a key determinant of neural circuit formation. In this issue of Neuron, Kawabe et al. demonstrate that the ubiquitin ligase Nedd4 promotes the branching of developing dendrites by targeting the small G protein Rap2. In a complementary study, Drinjakovic et al. show that Nedd4 promotes the branching of developing axons by ubiquitinating a different target,...
متن کاملLamellipodial actin branches out
Many cell types, including fi broblasts and epithelial cells, move forward by forming an actin-rich membrane protrusion, called a lamellipodium, at the front of the cell. In the early 1990s, researchers thought that lamellipodial protrusion was driven by the polymerization of linear actin fi laments. In two JCB papers published in 1997 and 1999, however, Tatyana Svitkina and colleagues revealed...
متن کاملMorphogenesis: FGF branches out
Signalling via tissue-specific receptors for fibroblast growth factor is important in tracheal branching and mesodermal patterning in Drosophila; both processes may involve a common primary response - detachment and directed migration of the target cells - that is conserved from worms to mammals.
متن کاملKidney development branches out.
For more than 40 years now, the developing kidney has served as a model paradigm for epithelial-mesenchymal interactions. The principles of inductive signaling, epithelial cell differentiation, and pattern formation are now being addressed with modern genetic and biochemical tools. In addition to the mammalian kidney organ culture model, both zebrafish and Xenopus laevis demonstrate great poten...
متن کاملLamellipodin branches out
M igrating cells move forward by harnessing the force of actin polymerization to form a protru-sive lamellipodium at the leading edge. A protein called Lamellipodin (Lpd) promotes lamellipodium formation, but how it does so is unclear. Law et al. reveal that Lpd generates membrane protrusions in association with a key regulator of actin branching called the Scar/WAVE complex and that this inter...
