Summary: Enables ephrin receptor activity and growth factor binding activity. Involved in several processes, including axonal fasciculation; ephrin receptor signaling pathway; and synaptic membrane adhesion. Acts upstream of or within cellular response to follicle-stimulating hormone stimulus; negative regulation of neuron projection development; and regulation of cell migration. Is active in GABA-ergic synapse and presynapse. Is expressed in several structures, including alimentary system; embryo mesenchyme; genitourinary system; nervous system; and sensory organ. Human ortholog(s) of this gene implicated in pancreatic cancer. Orthologous to human EPHA3 (EPH receptor A3). [provided by Alliance of Genome Resources, Dec 2024]

EPHA3 enhances macrophage autophagy and apoptosis by disrupting the mTOR signaling pathway in mice with endometriosis.
Title: EPHA3 enhances macrophage autophagy and apoptosis by disrupting the mTOR signaling pathway in mice with endometriosis.
In conclusion, PS1/gamma-secretase-dependent EphA3 cleavage mediates axon growth by regulating filament assembly through RhoA signaling and non-muscle myosin IIA (NMIIA), suggesting opposite roles of EphA3 on inhibiting (ligand-dependent) and promoting (receptor processing) axon growth in developing neurons.

Although EPHA3 was reported to be one of the most frequently mutated genes in colorectal tumors, our studies using inducible isogenic cell line systems, mouse models and large human tumor collections, did not reveal a major role of this EPH receptor on proliferation/motility/invasion of cancer cells, tumor initiation/progression/metastasis in mouse models or survival of colorectal cancer patients.

study delineates a mechanism in which NCAM promotes ephrin-A5-dependent clustering of EphA3 through interaction of the NCAM Ig2 domain and the EphA3 CRD, stimulating EphA3 autophosphorylation and RhoA signaling necessary for growth cone repulsion in GABAergic interneurons in vitro, which may extend to remodeling of axonal terminals of interneurons in vivo.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
