Ephb2 Gene Summary [Rat]
Predicted to enable several functions, including amyloid-beta binding activity; identical protein binding activity; and transmembrane signaling receptor activity. Involved in several processes, including cell junction assembly; positive regulation of nervous system development; and positive regulation of protein localization. Located in cell surface; dendritic spine; and neuronal cell body. Is active in glutamatergic synapse. Used to study irritable bowel syndrome and ulcerative colitis. Biomarker of irritable bowel syndrome and middle cerebral artery infarction. Human ortholog(s) of this gene implicated in blood platelet disease. Orthologous to human EPHB2 (EPH receptor B2).
