Summary: Enables copper ion transmembrane transporter activity. Involved in several processes, including adult chitin-containing cuticle pigmentation; copper ion import across plasma membrane; and intracellular copper ion homeostasis. Located in cytoplasm and plasma membrane. Is expressed in several structures, including epithelial tube; ganglia; gonad; gut section; and organism subdivision. Used to study Menkes disease and metal metabolism disorder. Human ortholog(s) of this gene implicated in Menkes disease; Wilson disease; X-linked distal spinal muscular atrophy 3; cutis laxa; and occipital horn syndrome. Orthologous to several human genes including ATP7B (ATPase copper transporting beta). [provided by Alliance of Genome Resources, Jan 2025]

ATP7 Mutation is associated with Menkes and Wilson Diseases, Motor Neuropathy, and Susceptibility to Alzheimer's Disease.
Title: In Vivo Modeling of the Pathogenic Effect of Copper Transporter Mutations That Cause Menkes and Wilson Diseases, Motor Neuropathy, and Susceptibility to Alzheimer's Disease.
This study showed ATP7A mutations impair copper metabolism resulting in neurodegeneration and neurodevelopmental defects in Menkes disease.
Title: Molecular basis of neurodegeneration and neurodevelopmental defects in Menkes disease.
Using a model of HD, we found that altered expression of Ctr1B or ATP7 in the brain, or modulation of dietary copper availability, significantly modified the phenotypes caused by human Htt exon1-polyQ expression.
Title: Huntington disease arises from a combinatory toxicity of polyglutamine and copper binding.
-regulation of ATP7 specifically in the SIFamide-expressing neurons resulted in male-male courtship behavior
Title: Functional significance of the copper transporter ATP7 in peptidergic neurons and endocrine cells in Drosophila melanogaster.
These results demonstrate DmATP7 is able to functionally compensate for the absence of ATP7A, with important trafficking motifs conserved in these distantly related orthologues.
Title: Conservation of copper-transporting P(IB)-type ATPase function.
These results highlight the role of DmATP7-mediated copper uptake in the neurodevelopment of Drosophila melanogaster and provide a framework for the analysis of potential gene interactions influencing Menkes disease.
Title: A Drosophila model of Menkes disease reveals a role for DmATP7 in copper absorption and neurodevelopment.
role for DmATP7 in export of copper from midgut cells.
Title: Expression and localisation of the essential copper transporter DmATP7 in Drosophila neuronal and intestinal tissues.
lethality observed in DmATP7 mutant flies is the earliest seen for any copper homeostasis gene
