CC -!- FUNCTION: Receptor tyrosine kinase which binds promiscuously
CC transmembrane ephrin-B family ligands residing on adjacent cells,
CC leading to contact-dependent bidirectional signaling into neighboring
CC cells. The signaling pathway downstream of the receptor is referred to
CC as forward signaling while the signaling pathway downstream of the
CC ephrin ligand is referred to as reverse signaling. Together with its
CC cognate ligand/functional ligand EFNB2 is involved in the regulation of
CC cell adhesion and cell migration, and plays a central role in heart
CC morphogenesis, angiogenesis and blood vessel remodeling and
CC permeability. EPHB4-mediated forward signaling controls cellular
CC repulsion and segregation from EFNB2-expressing cells (By similarity).
CC Involved in somitogenesis (PubMed:9765210).
CC {ECO:0000250|UniProtKB:P54760, ECO:0000269|PubMed:9765210}.
CC -!- CATALYTIC ACTIVITY:

CC -!- SIMILARITY: Belongs to the protein kinase superfamily. Tyr protein
