title: Calcium signalling: mitofusins promote interorganellar crosstalk.
abstract: Juxtaposition of the endoplasmic reticulum with mitochondria facilitates Ca(2+) fluxes between the organelles. However, the molecular basis of interorganellar tethering remains unknown. A recent report has identified a fundamental role for the dynamin-related mitofusins in the tethering mechanism, thereby ensuring rapid and high fidelity Ca(2+) signalling between the organelles.
