Summary: Enables P-type divalent copper transporter activity and superoxide dismutase copper chaperone activity. Involved in copper ion export and intracellular copper ion homeostasis. Acts upstream of or within several processes, including catecholamine metabolic process; erythrose 4-phosphate/phosphoenolpyruvate family amino acid metabolic process; and neuron differentiation. Located in several cellular components, including cytoplasmic vesicle membrane; neuronal cell body; and trans-Golgi network membrane. Is expressed in several structures, including genitourinary system; gut mucosa; liver; nervous system; and spleen. Used to study Menkes disease; X-linked distal spinal muscular atrophy 3; aortic aneurysm; and osteoarthritis. Human ortholog(s) of this gene implicated in Menkes disease; X-linked distal spinal muscular atrophy 3; cutis laxa; and occipital horn syndrome. Orthologous to human ATP7A (ATPase copper transporting alpha). [provided by Alliance of Genome Resources, Nov 2024]

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
