FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] Ephrin receptors and their ligands, the ephrins, mediate numerous developmental processes, particularly in the nervous system. Based on their structures and sequence relationships, ephrins are divided into the ephrin-A (EFNA) class, which are anchored to the membrane by a glycosylphosphatidylinositol linkage, and the ephrin-B (EFNB) class, which are transmembrane proteins. The Eph family of receptors are divided into two groups based on the similarity of their extracellular domain sequences and their affinities for binding ephrin-A and ephrin-B ligands. Ephrin receptors make up the largest subgroup of the receptor tyrosine kinase (RTK) family. This gene encodes a receptor for ephrin-B family members. [provided by RefSeq, Mar 2010]
PHENOTYPE: Homozygotes for a targeted null mutation exhibit defects in corpus callosum formation and impaired Paneth cell downward migration in the intestinal epithelium, resulting in scattered positioning along crypt and villus. [provided by MGI curators]
