Summaries for ATP1A2 Gene

Entrez Gene Summary for ATP1A2 Gene

  • 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.

GeneCards Summary for ATP1A2 Gene

ATP1A2 (ATPase Na+/K+ Transporting Subunit Alpha 2) is a Protein Coding gene. Diseases associated with ATP1A2 include Alternating Hemiplegia Of Childhood and Migraine, Familial Hemiplegic, 2. Among its related pathways are cAMP signaling pathway and Thyroid hormone signaling pathway. GO annotations related to this gene include nucleotide binding and cation-transporting ATPase activity. An important paralog of this gene is ATP12A.

UniProtKB/Swiss-Prot for ATP1A2 Gene

  • This is the catalytic component of the active enzyme, which catalyzes the hydrolysis of ATP coupled with the exchange of sodium and potassium ions across the plasma membrane. This action creates the electrochemical gradient of sodium and potassium, providing the energy for active transport of various nutrients.

Tocris Summary for ATP1A2 Gene

  • The Na+/K+ ATPase is a membrane protein that is composed of two subunits - alpha and beta. The pump maintains an essential electrochemical gradient within cells through the active transport of sodium (Na+) and potassium (K+) ions.

AT1A2_HUMAN
  • Alternating hemiplegia of childhood 1 (AHC1) [MIM:104290]: A rare syndrome of episodic hemi- or quadriplegia lasting minutes to days. Most cases are accompanied by dystonic posturing, choreoathetoid movements, nystagmus, other ocular motor abnormalities, autonomic disturbances, and progressive cognitive impairment. It is typically distinguished from familial hemiplegic migraine by infantile onset and high prevalence of associated neurological deficits that become increasingly obvious with age. {ECO:0000269 PubMed:15174025}. Note=The disease is caused by mutations affecting the gene represented in this entry.
  • Migraine, familial hemiplegic, 2 (FHM2) [MIM:602481]: A subtype of migraine with aura associated with hemiparesis in some families. Migraine is a disabling symptom complex of periodic headaches, usually temporal and unilateral. Headaches are often accompanied by irritability, nausea, vomiting and photophobia, preceded by constriction of the cranial arteries. Migraine with aura is characterized by recurrent attacks of reversible neurological symptoms (aura) that precede or accompany the headache. Aura may include a combination of sensory disturbances, such as blurred vision, hallucinations, vertigo, numbness and difficulty in concentrating and speaking. {ECO:0000269 PubMed:12539047, ECO:0000269 PubMed:12953268, ECO:0000269 PubMed:21352219, ECO:0000269 PubMed:23838748, ECO:0000269 PubMed:23918834}.
