Ephrin B1 is a protein that in humans is encoded by the EFNB1 gene. ^{[5] [6]} It is 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. ^[7]

Clinical significance

Mutations in this protein are responsible for most cases of craniofrontonasal syndrome. ^{[8] [9] [10]}

Interactions

EFNB1 has been shown to interact with SDCBP. ^[11]
