With‑no‑lysine kinase 3 (WNK3) is a serine/threonine kinase that functions by regulating downstream signaling molecules. WNK3 mainly regulates intracellular and extracellular Na+, Cl‑ and K+ levels by regulating downstream ion transporters, the disruption of which has been associated with cerebral ischemia, epilepsy, glioma and other diseases. In addition, WNK3 was demonstrated to regulate neuronal splicing factor RNA binding fox‑1 homolog‑1 to influence autism. Over the past 20 years, accumulating evidence has reported that dysfunctional WNK3 signaling was involved in the pathologies of various neurological disorders; therefore, WNK3 has become a promising therapeutic target for ameliorating the corresponding symptoms of such disorders. The present review aimed to provide a general overview of the expression patterns and physiological functions of WNK3 signaling and its pathophysiological roles in neurological diseases, such as epilepsy, ischemic brain injury, intracerebral hemorrhage, autism, glioma and schizophrenia.
