Recombinant Human ATP4A protein

• Cat.No.: ATP4A-975H
• Product Overview: Human ATP4A full-length ORF (AAI67780.1) recombinant protein without tag.

Specification

• Description: The protein encoded by this gene belongs to a family of P-type cation-transporting ATPases. The gastric H+, K+-ATPase is a heterodimer consisting of a high molecular weight catalytic alpha subunit and a smaller but heavily glycosylated beta subunit. This enzyme is a proton pump that catalyzes the hydrolysis of ATP coupled with the exchange of H(+) and K(+) ions across the plasma membrane. It is also responsible for gastric acid secretion. This gene encodes a catalytic alpha subunit of the gastric H+, K+-ATPase. [provided by RefSeq, Jul 2008]

Q&As

Is the polymorphism of Atp4a gene associated with abnormal gastric acid?

Yes, polymorphic variations in the Atp4a gene may be associated with the susceptibility and pathogenesis of gastric acid abnormalities, such as hyperacidity or hypoacidity.

Does Atp4a interact with proteins?

Atp4a interacts with other proteins in the Parietal cells of the gastric mucosa, such as parietal cell-associated proteins, to jointly regulate gastric acid production and secretion.

What is the mutation mechanism of Atp4a?

Mutations in Atp4a may lead to abnormal changes in its intracellular localization and function, and then affect the normal secretion of gastric acid.

How does Atp4a function under estrogen regulation?

Atp4a may be regulated by estrogen and regulate gastric acid secretion by affecting Atp4a expression and activity.

Which is the regulatory mechanism of Atp4a in gastric acid secretion?

Regulates gastric acid secretion through ATP binding and ion pump transport, and the specific mechanism involves the regulation of multiple signaling pathways and hormones.

What are the structural features of Atp4a?

Atp4a is a plasma wall protein containing several membrane channels and ATP-binding sites that regulate gastric acid secretion.
