该基因编码一个跨膜蛋白家族的成员，作为肾上腺素b家族蛋白的受体。与这个家族的其他成员不同，编码的蛋白质不包含功能性激酶结构域。这种蛋白的活性可以影响细胞的粘附和迁移。该基因在肿瘤发展过程中表达下调，提示该蛋白可能抑制肿瘤的侵袭和转移。选择性剪接导致多个转录变体。[由RefSeq提供，2013年7月]
This gene encodes a member of a family of transmembrane proteins that function as receptors for ephrin-B family proteins. Unlike other members of this family, the encoded protein does not contain a functional kinase domain. Activity of this protein can influence cell adhesion and migration. Expression of this gene is downregulated during tumor progression, suggesting that the protein may suppress tumor invasion and metastasis. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jul 2013]
