CC -!- FUNCTION: Copper ion transmembrane transporter involved in the export
CC of copper out of the cells, such as the efflux of hepatic copper into
CC the bile. {ECO:0000250|UniProtKB:P35670}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=ATP + Cu(+)(in) + H2O = ADP + Cu(+)(out) + H(+) + phosphate;
CC Xref=Rhea:RHEA:25792, ChEBI:CHEBI:15377, ChEBI:CHEBI:15378,
CC ChEBI:CHEBI:30616, ChEBI:CHEBI:43474, ChEBI:CHEBI:49552,
CC ChEBI:CHEBI:456216; EC=7.2.2.8;
CC Evidence={ECO:0000250|UniProtKB:P35670};
CC -!- SUBUNIT: Monomer. Interacts with COMMD1/MURR1 (By similarity).
CC Interacts with DCTN4, in a copper-dependent manner (By similarity).
CC Interacts with ATOX1 (By similarity). Interacts (via C-terminus) with
CC ZBTB16/PLZF (By similarity). {ECO:0000250|UniProtKB:P35670}.
CC -!- SUBCELLULAR LOCATION: Golgi apparatus, trans-Golgi network membrane
CC {ECO:0000250|UniProtKB:P35670}; Multi-pass membrane protein
CC {ECO:0000255}. Late endosome {ECO:0000250|UniProtKB:P35670}.
CC Note=Predominantly found in the trans-Golgi network (TGN). Not
CC redistributed to the plasma membrane in response to elevated copper
CC levels. {ECO:0000250|UniProtKB:P35670}.
CC -!- ALTERNATIVE PRODUCTS:
CC Event=Alternative splicing, Alternative initiation; Named isoforms=3;
CC Name=Long;
CC IsoId=Q64535-1; Sequence=Displayed;
CC Name=Short;
CC IsoId=Q64535-2; Sequence=VSP_000428;
CC Name=PINAM2;
CC IsoId=Q64535-3; Sequence=VSP_018666;
CC -!- TISSUE SPECIFICITY: Expressed in brain, liver, kidney, spleen and
CC stomach. In brain, detected in neuronal cells of the hippocampal
CC formation, olfactory bulbs, cerebellum, cerebral cortex and nuclei in
CC the brainstem. Isoform PINA is expressed during night in adult pineal
CC gland (pinealocytes) and retina. Isoform PINA is not detected in other
CC tissue.
CC -!- DEVELOPMENTAL STAGE: Isoform PINA is expressed during daytime in
CC embryonic pineal (postnatal day 2 and 7) and embryonic retinal pigment
CC epithelium (embryonic day 14.5 and postnatal day 16). Daytime
CC expression disappears in pineal at postnatal day 16 and in adult
CC retina.
CC -!- DOMAIN: Each HMA domain can bind a copper ion, they are tightly packed
CC and closely interact with each other. Wild-type ATP7B can usually be
CC loaded with an average 5.5 copper atoms per molecule (By similarity).
CC {ECO:0000250}.
CC -!- DISEASE: Note=Deficiency of Atp7b expression is the cause of the Long-
CC Evans Cinnamon (LEC) phenotype, inherited in an autosomal recessive
CC manner, characterized by excessive hepatic copper accumulation,
CC defective holoceruloplasmin biosynthesis, impaired biliary copper
CC excretion and the development of necrotizing hepatitis by 4 months of
CC age. {ECO:0000269|PubMed:7951327, ECO:0000269|PubMed:8037655}.
CC -!- MISCELLANEOUS: [Isoform Short]: Produced by alternative splicing. Does
CC not show copper transport activity. {ECO:0000305}.
CC -!- MISCELLANEOUS: [Isoform PINAM2]: Produced by alternative initiation at
CC Met-815 of isoform Long. Shows copper transport activity.
CC {ECO:0000305}.
CC -!- SIMILARITY: Belongs to the cation transport ATPase (P-type) (TC 3.A.3)
CC family. Type IB subfamily. {ECO:0000305}.
