The Notch signaling pathway can use its various ligands, receptors, and Fringe proteins to generate diverse intra- and intercellular signaling behaviors.
A new example of niche formation, revealing the mode of niche cell migration, implicates extrinsic sources of positional information, and uncovers the pathway required for stereotypical positioning of the niche.
Biophysical binding and structural prediction studies reveal that Tetraspanin12 directly binds the ligand Norrin, in a manner that is negatively cooperative with Norrin-Fzd4 binding and competitive with Norrin-LRP5/6 binding.
Single-molecule localization imaging shows that the Nipah virus fusion protein forms nanoscale clusters on cell and viral membranes that favor membrane fusion activation.
