Gene Summary

[ - ] NCBI Entrez Gene

Gene ID 2047 Official Symbol EPHB1
Locus N/A Gene Type protein-coding
Synonyms ELK; EPHT2; FLJ37986; Hek6; NET
Full Name EPH receptor B1
Description EPH receptor B1
Chromosome 3q21-q23
Also Known As eph tyrosine kinase 2; ephrin receptor EphB1; soluble EPHB1 variant 1
Summary 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 2 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. The protein encoded by this gene is a receptor for ephrin-B family members. [provided by RefSeq]
