腎上腺素受體及其配體，腎上腺素，介導許多發育過程，特別是在神經系統。根據其結構和序列關系，腎素被分為通過糖基磷脂酰肌醇連接錨定在膜上的腎素-A（efna）類和作為跨膜蛋白的腎素-B（efnb）類。EPH受體家族根據其胞外結構域序列的相似性及其與腎素A和腎素B配體結合的親緣關系分為2組。腎上腺素受體構成受體酪氨酸激酶（RTK）家族的最大亞群。該基因編碼的蛋白質與腎素B2結合，在血管發育中起重要作用。
Ephrin receptors and their ligands, the ephrins, mediate numerous developmental processes, particularly in the nervous system. Based on their structures and sequence relationships, ephrins are divided into the ephrin-A (EFNA) class, which are anchored to the membrane by a glycosylphosphatidylinositol linkage, and the ephrin-B (EFNB) class, which are transmembrane proteins. The Eph family of receptors are divided into 2 groups based on the similarity of their extracellular domain sequences and their affinities for binding ephrin-A and ephrin-B ligands. Ephrin receptors make up the largest subgroup of the receptor tyrosine kinase (RTK) family. The protein encoded by this gene binds to ephrin-B2 and plays an essential role in vascular development.
