Gene: EFNB1 (ephrin B1) Homo sapiens
Symbol: EFNB1
Name: ephrin B1
Description: The protein encoded by this gene is a type I membrane protein and a ligand of Eph-related receptor tyrosine kinases. It may play a role in cell adhesion and function in the development or maintenance of the nervous system. [provided by RefSeq, Jul 2008]
Type: protein-coding
RefSeq Status: REVIEWED
Also known as: CFND; CFNS; craniofrontonasal syndrome (craniofrontonasal dysplasia); EFB1; EFL-3; EFL3; ELK ligand; Elk-L; eph-related receptor tyrosine kinase ligand 2; ephrin-B1; EPLG2; LERK-2; LERK2; ligand of eph-related kinase 2; MGC8782
