Sodium/potassium-transporting ATPase subunit alpha-2 is a protein which in humans is encoded by the ATP1A2 gene.{{cite web |title=ATP1A2 - Sodium/potassium-transporting ATPase subunit alpha-2 precursor - Homo sapiens (Human) - ATP1A2 gene & protein |url=https://www.uniprot.org/uniprot/P50993 |website=www.uniprot.org |access-date=9 April 2022 |language=en}}{{cite web | title = Entrez Gene: ATP1A2 ATPase, Na+/K+ transporting, alpha 2 (+) polypeptide| url = https://www.ncbi.nlm.nih.gov/sites/entrez?Db=gene&Cmd=ShowDetailView&TermToSearch=477}}

Function

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 2 subunit.

Clinical significance

Mutations in ATP1A2 have been found to cause hemiplegic migraine and epilepsy in an autosomal dominant fashion, sometimes co-occurring in families.{{cite journal | vauthors = Papandreou A, Danti FR, Spaull R, Leuzzi V, Mctague A, Kurian MA | title = The expanding spectrum of movement disorders in genetic epilepsies | journal = Developmental Medicine and Child Neurology | volume = 62 | issue = 2 | pages = 178–191 | date = February 2020 | pmid = 31784983 | doi = 10.1111/dmcn.14407 | s2cid = 208498567 | url = https://discovery.ucl.ac.uk/id/eprint/10088482/1/Kurian_Papandreou%20DMCN%20Final_clean.pdf }} Additionally, it has been associated with an unusual form of migraine called alternating hemiplegia of childhood.{{cite journal | vauthors = Kanavakis E, Xaidara A, Papathanasiou-Klontza D, Papadimitriou A, Velentza S, Youroukos S | title = Alternating hemiplegia of childhood: a syndrome inherited with an autosomal dominant trait | journal = Developmental Medicine and Child Neurology | volume = 45 | issue = 12 | pages = 833–6 | date = December 2003 | pmid = 14667076 | doi = 10.1017/S0012162203001543 | url = http://www3.interscience.wiley.com/resolve/openurl?genre=article&issn=0012-1622&date=2003&volume=45&issue=12&spage=833 | url-access = subscription }}{{dead link|date=February 2019|bot=medic}}{{cbignore|bot=medic}}{{cite journal | vauthors = Swoboda KJ, Kanavakis E, Xaidara A, Johnson JE, Leppert MF, Schlesinger-Massart MB, Ptacek LJ, Silver K, Youroukos S | display-authors = 6 | title = Alternating hemiplegia of childhood or familial hemiplegic migraine?
