該基因屬于酪氨酸蛋白激酶家族的腎上腺素受體亞家族。eph和eph相關受體參與了發育事件的調節，特別是在神經系統中。eph亞家族的受體通常有一個單一的激酶結構域和一個胞外區域，包含一個富含cys的結構域和2個纖維連接蛋白iii型重復序列。根據其胞外結構域序列的相似性和結合ephrin-a和ephrin-b配體的親和力，ephrin受體可分為兩類。這個基因編碼一種結合腎上腺素a配體的蛋白質。已經描述了該基因的兩個選擇性剪接轉錄變體。[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 encodes a protein that binds ephrin-A ligands. Two alternatively spliced transcript variants have been described for this gene. [provided by RefSeq, Jul 2008]
