ATP1A4 - ATPase Na+/K+ transporting subunit alpha 4 Gene
Also Known as ATP1A1; ATP1AL2
Species: Homo sapiens
About ATP1A4
This gene has 6 transcripts (splice variants), 573 orthologues and 21 paralogues. Biased expression in testis (RPKM 7.3), brain (RPKM 2.1) and 4 other tissues.
Summary
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 4 subunit. Alternatively spliced transcript variants encoding different isoforms have been identified. [provided by RefSeq, Jul 2008]
