EPHA1（EPH receptor A1），癌症关联基因，基因ID：2041，该基因属于酪氨酸蛋白激酶家族的肾上腺素受体亚家族eph和eph相关受体参与了发育事件的调节，特别是在神经系统中。eph亚家族的受体通常有一个单一的激酶结构域和一个胞外区域，包含一个富含cys的结构域和2个纤维连接蛋白iii型重复序列。根据其胞外结构域序列的相似性和结合ephrin-A和ephrin-B配体的亲和力，ephrin受体可分为两类该基因在一些人类肿瘤细胞系中表达，并与肿瘤发生有关。[由RefSeq提供，2008年7月]This gene belongs to the ephrin receptor subfamily of the protein-tyrosine kinase family. EPH and EPH-related receptors have been implicated in mediating developmental events， particularly in the nervous system. Receptors in the EPH subfamily typically have a single kinase domain and an extracellular region containing a Cys-rich domain and 2 fibronectin type III repeats. The ephrin 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. This gene is expressed in some human cancer cell lines and has been implicated in carcinogenesis. [provided by RefSeq， Jul 2008]。
