EPHB1（EPH receptor B1），癌症关联基因，基因ID：2047，肾上腺素受体及其配体，即肾上腺素，介导许多发育过程，特别是在神经系统。根据它们的结构和序列关系，肾上腺素可分为通过糖基磷脂酰肌醇键固定在膜上的肾上腺素-A（EFNA）类和跨膜蛋白肾上腺素-B（EFNB）类。eph受体家族根据其胞外结构域序列的相似性和与ephrin-a和ephrin-b配体结合的亲和力可分为2类。肾上腺素受体是酪氨酸激酶（rtk）受体家族中最大的亚群。这个基因编码的蛋白质是肾上腺素b家族成员的受体。[由RefSeq提供，2008年7月]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 gen。
