function:May function actively to stimulate axon fasciculation. Induces compartmentalized signaling within a caveolae-like membrane microdomain when bound to the extracellular domain of its cognate receptor. This signaling event requires the activity of the Fyn tyrosine kinase.,similarity:Belongs to the ephrin family.,subcellular location:Compartmentalized in discrete caveolae-like membrane microdomains.,subunit:Binds to EPHB2 (By similarity). Binds to the receptor tyrosine kinases EPHA2, EPHA3 and EPHB1.,
