Gene: EFNB1 (ephrin B1) Homo sapiens
Symbol: EFNB1
Name: ephrin B1
Description: Predicted to have ephrin receptor binding activity. Predicted to be involved in axon guidance and ephrin receptor signaling pathway. Localizes to the plasma membrane. Implicated in craniofrontonasal syndrome and dysostosis.
Type: protein-coding
RefSeq Status: REVIEWED
