[5][6] The protein encoded by this gene belongs to the family of P-type cation transport ATPases and to the subfamily of Na+/K+-ATPases.

These gradients are essential for osmoregulation, for sodium-coupled transport of a variety of organic and inorganic molecules, and for electrical excitability of nerve and muscle.

[6] Mutations in ATP1A2 have been found to cause hemiplegic migraine and epilepsy in an autosomal dominant fashion, sometimes co-occurring in families.

[7] Additionally, it has been associated with an unusual form of migraine called alternating hemiplegia of childhood.
