Abstract:
Eph receptors constitute the largest family of tyrosine kinase receptors and, together with their plasma-membrane-bound ephrin ligands, have many important functions during development and adulthood. In contrast with most receptor tyrosine kinases, unidirectional signalling can originate from the ephrin ligands as well as from the Eph receptors. Furthermore, the concept of bidirectional signalling has emerged as an important mechanism by which Ephs and ephrins control the output signal in processes of cell-cell communication.
