ATP7B
-
Official Full Name
ATPase, Cu++ transporting, beta polypeptide
-
Overview
This gene is a member of the P-type cation transport ATPase family and encodes a protein with several membrane-spanning domains, an ATPase consensus sequence, a hinge domain, a phosphorylation site, and at least 2 putative copper-binding sites. This protein functions as a monomer, exporting copper out of the cells, such as the efflux of hepatic copper into the bile. Alternate transcriptional splice variants, encoding different isoforms with distinct cellular localizations, have been characterized. Mutations in this gene have been associated with Wilson disease (WD). -

Q&As (5)
Ask a questionATP7B facilitates copper transport from the cytoplasm to the Golgi apparatus, where copper is incorporated into proteins. It also mediates copper export from cells when copper levels are elevated, preventing toxicity.
ATP7B interacts with various proteins in the copper transport pathway. Disruptions in these interactions can lead to mislocalization of ATP7B and compromise its ability to regulate copper levels properly.
ATP7B ensures the proper supply of copper to enzymes involved in various cellular processes, including energy production and antioxidant defense. Dysregulation can disrupt these processes, affecting cell function.
ATP7B is crucial for copper excretion into bile, a process that contributes to systemic copper balance. Dysfunctional ATP7B results in impaired copper excretion, leading to the accumulation of copper in tissues.
Mutations in the ATP7B gene lead to impaired copper transport, causing copper accumulation in tissues. This is associated with Wilson's disease, a disorder characterized by copper toxicity, especially in the liver and brain.
