Protein attributes
| Sequence length | 984 AA. |
| Sequence status | Complete. |
| Sequence processing | The displayed sequence is further processed into a mature form. |
| Protein existence | Evidence at protein level. |
General annotation (Comments)
| 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. |
| Catalytic activity | ATP + a [protein]-L-tyrosine = ADP + a [protein]-L-tyrosine phosphate. |
| Subunit structure | 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 By similarity. |
| Subcellular location | |
| Tissue specificity | Preferentially expressed in brain. |
| Sequence similarities | Belongs to the protein kinase superfamily. Tyr protein kinase family. Ephrin receptor subfamily. Contains 2 fibronectin type-III domains. Contains 1 protein kinase domain. Contains 1 SAM (sterile alpha motif) domain. |
