Background: COMMD1

COMMD1, also known as MURR1 and the copper toxicosis gene product, is a ubiquitously expressed 21 kDa copper binding protein. It contains an N-terminal domain (aa 1-121) and C-terminal domain (aa 125-190) which are separated by a protease sensitive site. It forms high molecular weight oligomeric complexes both in solution and in association with phospholipid membranes. COMMD1 is found in the nucleus and cytoplasm as well as in endocytic vesicle membrane fractions. It binds and regulates the activity of a variety of proteins including the copper transporter Wilson disease protein (ATP7B), the delta ENaC epithelial cell sodium channel, the cystic fibrosis transmembrane regulator (CFTR), superoxide dismutase 1 (SOD1), XIAP, HIF-1 alpha, and Cullin RING ubiquitin ligases. COMMD1 promotes the ubiquitination and degradation of the RelA subunit of NFkB, thereby inhibiting its chromatin association and nuclear targeting as well as the replication of HIV in resting T cells. Within aa 37-135, human COMMD1 shares 94% aa sequence identity with mouse and rat COMMD1.
