Other Information

**Key Characteristics:** EPHA4 is a transmembrane receptor tyrosine kinase that belongs to the Eph family of receptors. It is characterized by its unique structure, which includes a characteristic immunoglobulin-like domain, seven transmembrane helices, and a tyrosine kinase domain. EPHA4 is primarily expressed in the nervous system, with notable expression in Purkinje cells, pyramidal neurons, and other brain-derived cells. **Pathways and Functions:** EPHA4 is involved in a wide range of signaling pathways, including: 1. **Axon guidance and fasciculation**: EPHA4 plays a crucial role in regulating axon growth, guidance, and fasciculation, particularly in the development of the nervous system. 2. **Cell adhesion and migration**: EPHA4-mediated signaling regulates cell adhesion, migration, and proliferation, influencing tissue development and homeostasis. 3. **Neurotransmission and synapse formation**: EPHA4 is involved in regulating neurotransmitter release, synaptic plasticity, and synapse formation. 4. **Immune responses**: EPHA4 has been implicated in modulating immune responses, including regulation of dendritic cell migration and T-cell activation. **Clinical Significance:** EPHA4 has significant implications in various immunological and neurological disorders, including: 1. **Multiple sclerosis**: EPHA4 has been shown to play a role in regulating axonal damage and repair in multiple sclerosis, a chronic autoimmune disease affecting the central nervous system. 2. **Neurodegenerative diseases**: EPHA4 has been implicated in the pathogenesis of neurodegenerative diseases, such as Alzheimer's disease, Parkinson's disease, and amyotrophic lateral sclerosis (ALS). 3. **Cancer**: EPHA4 has been linked to cancer progression and metastasis, particularly in brain and neuroendocrine tumors. 4. **Autoimmune disorders**: EPHA4 has been implicated in the pathogenesis of autoimmune disorders, such as rheumatoid arthritis and lupus. **Conclusion:** EPHA4 is a complex receptor tyrosine kinase that plays a multifaceted role in regulating various physiological and pathological processes. Its involvement in axon guidance, cell adhesion, neurotransmission, and immune responses makes it an attractive target for immunological research and therapeutic interventions. Further studies are needed to fully elucidate the mechanisms underlying EPHA4-mediated signaling and its implications in immunological disorders.
