title: ADAM and Eph: how Ephrin-signaling cells become detached.
abstract: Ephrin ligands presented on one cell surface associate with their receptors on the surface of a juxtaposed cell, often resulting in cell-cell repulsion. In this issue of Cell, Janes et al. (2005) show that the ephrin ligand can be proteolytically released from its membrane tether by a complex on the opposing cell composed of the ephrin receptor and an ADAM metalloprotease.
