Increased activity of hypoxia-inducible factor 1 is associated with early embryonic lethality in Commd1 null mice.

ABSTRACT: COMMD1 (previously known as MURR1) belongs to a novel family of proteins termed the copper metabolism gene MURR1 domain (COMMD) family. The 10 COMMD family members are well conserved between vertebrates, but the functions of most of the COMMD proteins are unknown. We recently established that COMMD1 is associated with the hepatic copper overload disorder copper toxicosis in Bedlington terriers. Recent in vitro studies indicate that COMMD1 has multiple functions, including sodium transport and NF-kappaB signaling. To elucidate the function of Commd1 in vivo, we generated homozygous Commd1 null (Commd1(-/-)) mice. Commd1(-/-) embryos died in utero between 9.5 and 10.5 days postcoitum (dpc), their development was generally retarded, and placenta vascularization was absent. Microarray analysis
