EPHA8
EPHA8 (Ephrin type-A receptor 8) 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 Neuroendocrine tumours and Thyroid cancer. 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.
Biology
Receptor tyrosine kinase which binds promiscuously GPI-anchored ephrin-A 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. The GPI-anchored ephrin-A EFNA2, EFNA3, and EFNA5 are able to activate EPHA8 through phosphorylation. With EFNA5 may regulate integrin-mediated cell adhesion and migration on fibronectin substrate but also neurite outgrowth. During development of the nervous system also plays a role in axon guidance. Downstream effectors of the EPHA8 signalling pathway include FYN which promotes cell adhesion upon activation by EPHA8 and the MAP kinases in the stimulation of neurite outgrowth. Location: Cell membrane; Cell projection; Early endosome membrane (UniProt). Locus 1p36.12 (HGNC).
