COMMD8 is a member of the COMMD family. Members of this family are a group of evolutionary conserved proteins that share a common COMM domain at the extreme C-terminus, which provides an interface for protein-protein interactions. Most COMMD proteins play a role in the regulation of NF˚B and, despite their similarities, seem to function in unique and non-redundant pathways. COMMD proteins may also play a role in the function of epithelial sodium channels, cell proliferation, copper homeostasis and in the regulation of the ubiquitin pathway. COMMD8 also contains 1 COMM domain and is widely expressed with highest expression in thyroid.
