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 it is involved in the regulation of cell adhesion and migration, and plays a central role in heart morphogenesis, angiogenesis and blood vessel remodeling and permeability.
EPHB4-mediated forward signaling controls cellular repulsion and segregation from EFNB2-expressing cells
Heterotetramer upon binding of the ligand. The heterotetramer is composed of an ephrin dimer and a receptor dimer. Oligomerization is probably required to induce biological responses (By similarity).
Interacts with RASA1; the interaction depends on EPHB4 tyrosine-phosphorylation (PubMed:30578106)
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
A form of primary lymphedema, a disease characterized by swelling of body parts due to developmental anomalies and functional defects of the lymphatic system. Patients with lymphedema may suffer from recurrent local infections. LMPHM7 is an autosomal dominant form with variable expressivity.
Some individuals present with severe non-immune hydrops fetalis, which may cause perinatal demise or fully resolve after the neonatal period. Others present with no edema and have milder clinical features, such as atrial septal defect or varicose veins as adults.
An autosomal dominant disorder characterized by multiple, round to oval or more irregularly shaped macules that are pinkish red in color and are randomly distributed across the body. These capillary malformations are associated with either arteriovenous malformation, arteriovenous fistula, or Parkes Weber syndrome.
