Example Gene Annotation by DO, OMIM and GO. ATP7B ATPase, Cu++ transporting, beta polypeptide. GeneID: 540. 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). DOID. Breast Carcinoma, Carcinoma, Congenital Abnormality, Disorder of copper metabolism, Esophageal carcinoma, Hepatolenticular Degeneration, Liver diseases, Malignant neoplasm of ovary, Primary carcinoma of the liver cells, Stomach Carcinoma.
