Abstract

COMMD3 is a member of the COMMD family defined by the presence of a conserved and unique motif termed the COMM (copper metabolism gene MURR1) domain, which functions as an interface for protein-protein interactions [ 1 ]. COMMD3 modulates Na+ transport in epithelial cells by regulation of apical cell surface expression of amiloride-sensitive sodium channel (ENaC) subunits [ 2 ].
