About ATP1A2

Cytogenetic location: 1q23.2 Genomic coordinates (GRCh38): 1:160,115,759-160,143,591 (from NCBI)

This gene has 8 transcripts (splice variants), 206 orthologues, 21 paralogues and is associated with 8 phenotypes. Biased expression in brain (RPKM 189.3), heart (RPKM 37.1) and 3 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 2 subunit. Mutations in this gene result in familial basilar or hemiplegic migraines, and in a rare syndrome known as alternating hemiplegia of childhood.
