Automated description from the Alliance of Genome Resources (Release 7.0.0)
Enables ephrin receptor binding activity. Involved in several processes, including ephrin receptor signaling pathway; heart valve morphogenesis; and negative regulation of dendritic spine morphogenesis. Acts upstream of or within several processes, including negative regulation of thymocyte apoptotic process; nervous system development; and regulation of MAPK cascade. Located in plasma membrane. Is expressed in several structures, including alimentary system; brain; cardiovascular system; genitourinary system; and sensory organ. Orthologous to human EFNA1 (ephrin A1).
