... a fourfold nature. Here we describe the quatrefoil complexes and other, unrelated, tethering complexes, and discuss ideas about their function. We propose that vesicle tethering may have separate kinetic and thermodynamic elements and that it may be usefully divided into events upstream and downstream...
