CATEGORY

enzyme , receptor

SUBCELLULAR LOCALIZATION	extracellular
	plasma membrane

basic FUNCTION	involved in short-range contact-mediated axonal guidance
	key players in controlling these cell movements in many tissues and at multiple stages of patterning
	suppresses motility through regulation of Rho GTPases in rhabdomyosarcoma cells
	mediate processes involving cell-cell contact, including cellular adhesion or repulsion, developmental remodeling and neuronal mapping
	EPHA3 and PROM1 may play an important role in the development and progression of colorectal tumours
