the CAPOS mutation caused a weaker voltage dependence of the pumping rate and a stronger inhibition by cytoplasmic K(+) than the WT enzyme, which together with the reduced Na(+) affinity of the cytoplasmic-facing sites precluded proper pump activation under physiological conditions.
ATP1A3 gene is the main causative gene of AHC. Three hotspot mutations, D801N, E815K and G947R, were found. Hotspot mutation E815K is associated with the most severe phenotype, which presented an earlier age at the time of the first paroxysmal manifestation and first hemiplegic event, severer developmental delay and a greater proportion of epilepsy

study confirms that the specific c.2452G>A mutation in the ATP1A3 gene is associated with the CAPOS syndrome in pedigrees of different ethnic backgrounds; also the first report showing the co-occurrence of hemiplegic migraine and CAPOS syndrome in a patient with ATP1A3 mutations
Our results, demonstrate a highly variable clinical phenotype in patients with alternating hemiplegia of childhood that correlates with certain mutations and possibly clusters within the ATPase Na+/K+ transporting subunit alpha 3 gene.
nvestigated a large dystonia family from New Zealand in which only females were affected; found a novel, likely disease-causing, three base-pair deletion (c.443_445delGAG, p.Ser148del) in ATP1A3 in this family by combining genome and exome sequencing
Common variants of ATP1A3 were associated with susceptibility to generalized epilepsy in a Chinese population.
This study further expands the number and spectrum of ATP1A3 mutations associated with Alternating Hemiplegia of Childhood and confirms a more deleterious effect of the E815K mutation on selected neurologic outcomes.
This study demonstrated that the ATP1A3 protein was altered in auditory cortex patient with schizophreia.
interactions of alpha3-NKA with extracellular alpha-syn assemblies reduce its pumping activity as its mutations in RDP/AHC.
Alternating hemiplegia of childhood is a rare disorder caused by de novo mutations in the ATP1A3 gene, expressed in neurons and cardiomyocytes.
The amylospheroids target is neuron-specific Na(+)/K(+)-ATPase alpha3 subunit (NAKalpha3).
Na(+)/K(+)-ATPase alpha3 does not reside within the core circadian molecular clockwork, but Myk/+ mice exhibit concomitant disruption in circadian rhythms and mood. The Myshkin model demonstrates profound circadian and light-responsive behavioral alterations independent of molecular clock disruption.
The animal model containing a E815K mutation in ATP1A3, manifests clinical and neurophysiological features of the most severe form of alternating hemiplegia of childhood.

A heterozygous knock-in mouse harboring the D801Y mutation in ATP1A3 was generated. This mice displayed hyperactivity, increased sensitivity to chemically induced epileptic seizures and cognitive deficits. The findings reveal the functional significance of ATP1A3 gene in the control of spatial learning and memory and suggest a link to GABA transmission.
Knockout of sodium pump alpha3 subunit gene (Atp1a3(-/-)) results in perinatal seizure and defective respiratory rhythm generation
Mice harboring a heterozygous hot spot disease mutation, D801Y suffer abrupt hypothermia-induced dystonia. D-to-Y mutation abolished pump-mediated Na+/K+ exchange.

findings show Atp1a3-deficient heterozygotes exhibited shorter stride length at 4 weeks of age without stress and at later stages under chronic restraint stress; Atp1a3 was widely expressed in the brain and spinal cord of young mice; expression pattern was compatible with movement abnormalities under lack of one of alleles

The protein encoded by this gene belongs to the family of P-type cation transport ATPases, and to the subfamily of Na+/K+ -ATPases. Na+/K+ -ATPase is an integral membrane protein responsible for establishing and maintaining the electrochemical gradients of Na and K ions across the plasma membrane. 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. This enzyme is composed of two subunits, a large catalytic subunit (alpha) and a smaller glycoprotein subunit (beta). The catalytic subunit of Na+/K+ -ATPase is encoded by multiple genes. This gene encodes an alpha 3 subunit. Alternatively spliced transcript variants encoding different isoforms have been found for this gene.
