General annotation (Comments)
| Function | Kinase-defective receptor for members of the ephrin-B family. Binds to ephrin-B1 and ephrin-B2. Modulates cell adhesion and migration by exerting both positive and negative effects upon stimulation with ephrin-B2. Inhibits JNK activation, T cell receptor-induced IL-2 secretion and CD25 expression upon stimulation with ephrin-B2. Ref.10 Ref.11 |
| Subunit structure | Interacts with CBL and EPHB1. Interacts with FYN; this interaction takes place in a ligand-independent manner. Ref.9 Ref.11 |
| Subcellular location | |
| Tissue specificity | Expressed in brain. Expressed in non invasive breast carcinoma cell lines (at protein level). Strong expression in brain and pancreas, and weak expression in other tissues, such as heart, placenta, lung, liver, skeletal muscle and kidney. Expressed in breast non invasive tumors but not in metastatic lesions. Isoform 3 is expressed in cell lines of glioblastomas, anaplastic astrocytomas, gliosarcomas and astrocytomas. Isoform 3 is not detected in normal tissues. Ref.1 Ref.12 Ref.13 |
| Domain | The protein kinase domain is predicted to be catalytically inactive. Its extracellular domain is capable of promoting cell adhesion and migration in response to low concentrations of ephrin-B2, but its cytoplasmic domain is essential for cell repulsion and inhibition of migration induced by high concentrations of ephrin-B2. |
| Post-translational modification | Ligand-binding increases phosphorylation on tyrosine residues. Phosphorylation on tyrosine residues is mediated by transphosphorylation by the catalytically active EPHB1 in a ligand-independent manner. Tyrosine phosphorylation of the receptor may act as a switch on the functional transition from cell adhesion/attraction to de-adhesion/repulsion. |
| Sequence similarities | Belongs to the protein kinase superfamily. Tyr protein kinase family. Ephrin receptor subfamily. Contains 1 Eph LBD (Eph ligand-binding) domain. Contains 2 fibronectin type-III domains. Contains 1 protein kinase domain. Contains 1 SAM (sterile alpha motif) domain. |
| Sequence caution | The sequence AAD03058.1 differs from that shown. Reason: Erroneous initiation. Translation N-terminally extended. The sequence AAI10608.2 differs from that shown. Reason: Erroneous initiation. Translation N-terminally extended. The sequence AAP20939.1 differs from that shown. Reason: Erroneous initiation. Translation N-terminally extended. The sequence BAA21560.1 differs from that shown. Reason: Erroneous initiation. Translation N-terminally extended. The sequence EAL23775.1 differs from that shown. Reason: Erroneous gene model prediction. The sequence EAW51902.1 differs from that shown. Reason: Erroneous gene model prediction. |
