EPHB3 (Ephrin type-B receptor 3) is a protein kinase, an enzyme that switches other proteins on by adding phosphate groups. The public catalogues list it as a drug target, and an approved or late-stage drug is recorded against it. Tied to Thyroid cancer and Neuroendocrine tumours. This dossier gathers the 0 products (0 approved), 0 trials, 0 pathways and 0 resistance routes in the corpus that involve it, with external identifiers so it can be joined to UniProt, ChEMBL, Open Targets and the rest of biology.
Receptor tyrosine kinase which binds promiscuously transmembrane ephrin-B family ligands residing on adjacent cells, leading to contact-dependent bidirectional signalling into neighboring cells. The signalling pathway downstream of the receptor is referred to as forward signalling while the signalling pathway downstream of the ephrin ligand is referred to as reverse signalling. Generally has an overlapping and redundant function with EPHB2. Like EPHB2, functions in axon guidance during development regulating for instance the neurons forming the corpus callosum and the anterior commissure, 2 major interhemispheric connections between the temporal lobes of the cerebral cortex. In addition to its role in axon guidance also plays an important redundant role with other ephrin-B receptors in development and maturation of dendritic spines and the formation of excitatory synapses. Controls other aspects of development through regulation of cell migration and positioning. Location: Cell membrane; Cell projection, dendrite (UniProt). Locus 3q27.1 (HGNC).
