Ephrin-B1 is a protein that in humans is encoded by the EFNB1 gene.^[1][2]

This gene encodes a member of the ephrin family. The encoded protein 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.^[3]

Mutations in this protein are responsible for most cases of craniofrontonasal syndrome.^[4][5][6]

Interactions

EFNB1 has been shown to interact with SDCBP.^[7]
