Eph receptor A3 also known as EphA3 is a member of the ephrin receptor subfamily of protein-tyrosine kinases. This receptor with a mass of approximately 120 kDa plays a role in cell-cell communication mainly by interacting with ephrin-A ligands. EphA3 is expressed in various tissues including the nervous system developing tissues and some adult tissues like the lungs and prostate. Its localization varies with the developmental stage and tissue type reflecting its role in numerous processes.
Biological function summary
EphA3 influences cellular organization movement and positioning through its involvement in contact-dependent signaling. It acts as part of a larger receptor-ligand complex which mediates bidirectional signaling between cells. This interaction generally leads to changes in the cytoskeleton impacting cell shape and locomotion. EphA3’s signaling can regulate developmental processes such as axon guidance angiogenesis and tissue boundary formation.
Pathways
EphA3 modulates various important signaling pathways such as the PI3K/AKT pathway and the Rho family GTPase pathway. It interacts with proteins like Ephrin-A5 and other Eph receptors coordinating complex cellular signaling networks. These interactions contribute to the regulation of cell proliferation survival and migration influencing tissue patterning and organ development.
EphA3 has associations with cancer and neurological disorders. It has ties to various cancers like leukemia where it is implicated in proliferation and migration of malignant cells. In the context of neurological conditions EphA3 plays a role in neurodevelopmental disorders. In these diseases connections with other ephrin receptors and proteins involved in cell signaling become critical as they influence pathogenic pathways.
