Ephrins are cell-surface tethered guidance cues that bind to Eph receptor tyrosine kinases in trans on opposing cells. In the developing nervous system, the Eph-ephrin signaling system controls a large variety of cellular responses including contact-mediated attraction or repulsion, adhesion or de-adhesion, and migration.
Eph-ephrin signaling can be bidirectional, and is subject to modulation by ectodomain cleavage of ephrins and by Eph-ephrin endocytosis.
