ATP7B Blocking Peptide – The purity is >90%,tested by HPLC and MS. Purity

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). [provided by RefSeq, Jul 2008]

ATP7B: Involved in the export of copper out of the cells, such as the efflux of hepatic copper into the bile. Monomer. Interacts with COMMD1/MURR1. Most abundant in liver and kidney and also found in brain. Isoform 2 is expressed in brain but not in liver. The cleaved form WND/140 kDa is found in liver cell lines and other tissues. Belongs to the cation transport ATPase (P-type) (TC 3.A.3) family. Type IB subfamily. 4 isoforms of the human protein are produced by alternative splicing.
