Function [CC]:

Receptor tyrosine kinase which binds promiscuously transmembrane ephrin-B family ligands residing on adjacent cells, leading to contact-dependent bidirectional signaling into neighboring cells. The signaling pathway downstream of the receptor is referred to as forward signaling while the signaling pathway downstream of the ephrin ligand is referred to as reverse signaling. Together with its cognate ligand/functional ligand EFNB2 plays a central role in heart morphogenesis and angiogenesis through regulation of cell adhesion and cell migration. EPHB4-mediated forward signaling controls cellular repulsion and segregation form EFNB2-expressing cells. Plays also a role in postnatal blood vessel remodeling, morphogenesis and permeability and is thus important in the context of tumor angiogenesis. {ECO:0000269|PubMed:12734395, ECO:0000269|PubMed:16424904, ECO:0000269|PubMed:27400125}.

Tissue Specificity:

Abundantly expressed in placenta but also detected in kidney, liver, lung, pancreas, skeletal muscle and heart. Expressed in primitive and myeloid, but not lymphoid, hematopoietic cells. Also observed in cell lines derived from liver, breast, colon, lung, melanocyte and cervix. {ECO:0000269|PubMed:8188704}.

Disease:

Hydrops fetalis, non-immune, and/or atrial septal defect (HFASD) [MIM:617300]: A form of non-immune hydrops fetalis, a condition characterized by fluid accumulation in at least 2 fetal compartments, including abdominal cavities, pleura, and pericardium, or in body tissue. The majority of hydrops fetalis cases are non-immune conditions that present with generalized edema of the fetus. Approximately 15% of non-immune cases result from a lymphatic abnormality. HFASD is an autosomal dominant, lymphatic-related form with variable expressivity. Some patients suffer from severe manifestations that can result in early death, whereas others have milder clinical features, such as atrial septal defect or varicose veins as adults. The hydrops and/or swelling improves spontaneously in those who survive the neonatal period. {ECO:0000269|PubMed:27400125}. Note=The disease may be caused by mutations affecting the gene represented in this entry.
