Catalytic activity:ATP + a [protein]-L-tyrosine = ADP + a [protein]-L-tyrosine phosphate. ,Function:Receptor for members of the ephrin-B family. Binds to ephrin-B1 , -B2 and -B3. May be involved in cell-cell interactions in the nervous system. ,similarity:Belongs to the protein kinase superfamily. Tyr protein kinase family. Ephrin receptor subfamily. ,similarity:Contains 1 protein kinase domain. ,similarity:Contains 1 SAM (sterile alpha motif) domain. ,similarity:Contains 2 fibronectin type-III domains. ,subunit:The ligand-activated form interacts with GRB2 , GRB10 and NCK through their respective SH2 domains. The GRB10 SH2 domain binds EPHB1 through Tyr-928 , while GRB2 binds residues within the catalytic domain. Interacts with EPHB6. The NCK SH2 domain binds EPHB1 through Tyr-594. Interacts with PRKCABP. ,tissue specificity:Preferentially expressed in brain. ,
