Description
COMMD1, also known as copper metabolism MuRR1 domain-containing protein 1, is a 190 amino acid protein responsible for inhibition of TNF-induced NFkB p50 and has a suggested role in facilitation of biliary copper excretion within hepatocytes. High expression is found in liver tissue, with lower expressions in lung, heart, kidney and brain tissue. This protein interacts directly with COMMD6 and ATP7B, and indirectly with IkB-beta and COMMD7. Recombinant human COMMD1 protein, fused to His-tag at N-terminus, was expressed in E.coli and purified by using conventional chromatography techniques
