EPHA7 (Ephrin type-A receptor 7) is a protein kinase, an enzyme that switches other proteins on by adding phosphate groups. The public catalogues list it as a drug target, an oncogene driver and a tumour suppressor, and an approved or late-stage drug is recorded against it. Tied to Thyroid cancer, Neuroendocrine tumours, Colorectal cancer and 2 more.
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. Among GPI-anchored ephrin-A ligands, EFNA5 is a cognate/functional ligand for EPHA7 and their interaction regulates brain development modulating cell-cell adhesion and repulsion.
Open Targets scores its association with cancer at 0.70 (direct and indirect evidence; datatypes literature 0.94, genetic association 0.28, somatic mutation 0.50, clinical 0.93). IntOGen calls it a driver in 3 cohorts (1 activating, 2 loss-of-function), covering Colorectal Adenocarcinoma, Hepatocellular Carcinoma, Lung Adenocarcinoma.

No product in this corpus aims at EPHA7 yet. Kinases are switched on by binding ATP inside the cell, so most drugs are small molecules shaped to plug that ATP pocket.
Tumour-specific alteration: the catalogues call it an oncogene driver (IntOGen cohort analysis finds it activated more often than chance) and a tumour suppressor (IntOGen finds it knocked out more often than chance), so the direction differs between cohorts but the alteration is somatic either way; what a medicine would aim at or exploit is the altered form or its loss, absent from normal cells; no corpus medicine is aimed at it yet. HPA EPHA7: RNA tissue enriched (parathyroid gland 66 nTPM); high antibody staining in 8 normal tissues; highest cancer staining pancreatic cancer (1 of 8 high). Distribution: 5 cancer families in the corpus carry a prevalence row, label threshold or catalogue link for it (Thyroid cancer, Neuroendocrine tumours, Colorectal cancer, Hepatocellular carcinoma, Lung cancer (all types)); Open Targets associates it with 1 specific cancer type at or above 0.5 (medullary thyroid gland carcinoma).

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. Among GPI-anchored ephrin-A ligands, EFNA5 is a cognate/functional ligand for EPHA7 and their interaction regulates brain development modulating cell-cell adhesion and repulsion. Has a repellent activity on axons and is for instance involved in the guidance of corticothalamic axons and in the proper topographic mapping of retinal axons to the colliculus. May also regulate brain development through a caspase(CASP3)-dependent proapoptotic activity. Forward signalling may result in activation of components of the ERK signalling pathway including MAP2K1, MAP2K2, MAPK1 and MAPK3 which are phosphorylated upon activation of EPHA7. Location: Cell membrane (UniProt). Locus 6q16.1 (HGNC).
