ATP12A - ATPase H+/K+ transporting non-gastric alpha2 subunit Gene
Also Known as HK; ATP1AL1; H-K-ATPase
Species: Homo sapiens
About ATP12A
This gene has 2 transcripts (splice variants), 169 orthologues and 21 paralogues. Biased expression in esophagus (RPKM 7.0), kidney (RPKM 4.1) and 5 other tissues.
Summary
The protein encoded by this gene belongs to the family of P-type cation transport ATPases. This gene encodes a catalytic subunit of the ouabain-sensitive H+/K+ -ATPase that catalyzes the hydrolysis of ATP coupled with the exchange of H(+) and K(+) ions across the plasma membrane. It is also responsible for potassium absorption in various tissues. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jun 2010]
