'''Solution Structure of the N-terminal domain of COMMD1 (Murr1)'''<br />


==Overview==
==Solution Structure of the N-terminal domain of COMMD1 (Murr1)==
COMMD1 is the prototype of a new protein family that plays a role in, several important cellular processes, including NF-kappaB signaling, sodium transport, and copper metabolism. The COMMD proteins interact with, one another via a conserved C-terminal domain, whereas distinct functions, are predicted to result from a variable N-terminal domain. The COMMD, proteins have not been characterized biochemically or structurally. Here, we present the solution structure of the N-terminal domain of COMMD1, (N-COMMD1, residues 1-108). This domain adopts an alpha-helical structure, that bears little resemblance to any other helical protein. The compact, nature of N-COMMD1 suggests that full-length COMMD proteins are modular, consistent with specific functional properties for each domain., Interactions between N-COMMD1 and partner proteins may occur via, complementary electrostatic surfaces. These data provide a new foundation, for biochemical characterization of COMMD proteins and for probing COMMD1, protein-protein interactions at the molecular level.

== Function ==
[https://www.uniprot.org/uniprot/COMD1_HUMAN COMD1_HUMAN] Promotes ubiquitination of NF-kappa-B subunit RELA and its subsequent proteasomal degradation. Down-regulates NF-kappa-B activity. Down-regulates SOD1 activity by interfering with its homodimerization. Plays a role in copper ion homeostasis. Can bind one copper ion per monomer. May function to facilitate biliary copper excretion within hepatocytes.<ref>PMID:14685266</ref> <ref>PMID:15799966</ref> <ref>PMID:16573520</ref> <ref>PMID:17309234</ref> <ref>PMID:17183367</ref> <ref>PMID:20048074</ref> <ref>PMID:20595380</ref>

== Publication Abstract from PubMed ==
COMMD1 is the prototype of a new protein family that plays a role in several important cellular processes, including NF-kappaB signaling, sodium transport, and copper metabolism. The COMMD proteins interact with one another via a conserved C-terminal domain, whereas distinct functions are predicted to result from a variable N-terminal domain. The COMMD proteins have not been characterized biochemically or structurally. Here, we present the solution structure of the N-terminal domain of COMMD1 (N-COMMD1, residues 1-108). This domain adopts an alpha-helical structure that bears little resemblance to any other helical protein. The compact nature of N-COMMD1 suggests that full-length COMMD proteins are modular, consistent with specific functional properties for each domain. Interactions between N-COMMD1 and partner proteins may occur via complementary electrostatic surfaces. These data provide a new foundation for biochemical characterization of COMMD proteins and for probing COMMD1 protein-protein interactions at the molecular level.
