CC   -!- FUNCTION: Cell surface GPI-bound ligand for Eph receptors, a family of
CC       receptor tyrosine kinases which are crucial for migration, repulsion
CC       and adhesion during neuronal, vascular and epithelial development.
CC       Binds promiscuously Eph receptors residing on adjacent cells, leading
CC       to contact-dependent bidirectional signaling into neighboring cells.
CC       The signaling pathway downstream of the receptor is referred to as
CC       forward signaling while the signaling pathway downstream of the ephrin
CC       ligand is referred to as reverse signaling. With the EPHA2 receptor may
CC       play a role in bone remodeling through regulation of osteoclastogenesis
CC       and osteoblastogenesis (By similarity). {ECO:0000250}.
CC   -!- SUBUNIT: Binds to the receptor tyrosine kinases EPHA3, EPHA4 and EPHA5.
CC       Interacts with EPHA8; activates EPHA8 (By similarity). {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000305}; Lipid-anchor, GPI-
CC       anchor {ECO:0000305}.
CC   -!- TISSUE SPECIFICITY: Expressed in a gradient across the tectum being
CC       more strongly expressed at the posterior pole.
CC   -!- SIMILARITY: Belongs to the ephrin family. {ECO:0000255|PROSITE-
CC       ProRule:PRU00884}.
