EPH receptor A4 (ephrin type-A receptor 4) is a protein that in humans is encoded by the EPHA4 gene.[5][6]

This gene belongs to the ephrin receptor subfamily of the protein-tyrosine kinase family. EPH and EPH-related receptors have been implicated in mediating developmental events, particularly in the nervous system. Receptors in the EPH subfamily typically have a single kinase domain and an extracellular region containing a Cys-rich domain and 2 fibronectin type III repeats. The ephrin receptors are divided into 2 groups based on the similarity of their extracellular domain sequences and their affinities for binding ephrin-A and ephrin-B ligands.[6]

In 2012, a publication in Nature Medicine revealed a connection between EPHA4 and the neurodegenerative disease Amyotrophic lateral sclerosis (ALS), where a defective gene allows ALS patients to live considerably longer than patients with an intact gene. This opens up for development of treatment for this currently untreatable disease.
