ATP7B (human)

Overview
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. Note: This description may include information from UniProtKB.
