COMM_Domain containing protein 1, also called Murr1. Murr1/Commd1 is a protein involved in copper homeostasis, which has also been identified as a regulator of the human delta epithelial sodium channel. The COMM Domain is found at the C-terminus of a variety of proteins; presumably all COMM_Domain containing proteins are located in the nucleus and the COMM domain plays a role in protein-protein interactions. Several family members have been shown to bind and inhibit NF-kappaB.
