Scientific Data Images for Human COMMD1 Antibody

Detection of Human COMMD1 antibody by Western Blot.

Detection of Human COMMD1 by Western Blot.

Western blot shows lysates of U2OS human osteosarcoma cell line, HepG2 human hepatocellular carcinoma cell line, and human placenta tissue. PVDF membrane was probed with 0.2 µg/mL of Mouse Anti-Human COMMD1 Monoclonal Antibody (Catalog # MAB7526) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF018). A specific band was detected for COMMD1 at approximately 20 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.
COMMD1 antibody in U2OS Human Cell Line by Immunocytochemistry (ICC).

COMMD1 in U2OS Human Cell Line.

COMMD1 was detected in immersion fixed U2OS human osteosarcoma cell line using Mouse Anti-Human COMMD1 Monoclonal Antibody (Catalog # MAB7526) at 8 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Mouse IgG Secondary Antibody (red; Catalog # NL007) and counterstained with DAPI (blue). Specific staining was localized to cytoplasm and nuclei. View our protocol for Fluorescent ICC Staining of Cells on Coverslips.

LDLR associates with COMMD1 and the WASH complex.(a) Human embryonic kidney 293T (HEK293T) cells were transfected with constructs expressing Flag-LDLR with either COMMD1-GST or GST alone. Interaction with COMMD1 was detected via pull-down assay using glutathione sepharose beads. (b) HEK293T cells were transfected with Flag-LDLR vector, and interaction with endogenous COMMD1 was detected by immunoprecipitation with rabbit anti-Flag-antibody. (c) Colocalization of LDLR (red) and COMMD1 (green) in Commd1f/f MEFs examined by immunofluorescence staining. Representative images are shown; scale bar, 5μm. LDLR (red) and COMMD1 (green) was stained in COMMD1-deficient MEFs (Commd1−/−) and imaged by confocal fluorescence microscopy. COMMD1 levels in Commd1f/f and in Commd1−/− MEFs determined by immunoblot analysis. (d) Liver of a WT chow-fed mouse was homogenized and loaded on a continuous 10–40% sucrose gradient. Fractions were separated by ultracentrifugation and immunoblotted using antibodies against COMMD1, LDLR, WASH1, FAM21, VPS35 and CCDC22. The figure represents results of three independent experiments. (e) HEK293T cells were transfected with Ha-COMMD1 construct together with GST alone, GST-LDLRct (GST-tagged cytosolic domain of LDLR) or GST-LDLRct Y807A (GST-tagged mutated cytosolic domain of LDLR). Pull-down assay was performed to study the interaction between LDLRct and COMMD1. (f) Lysates of Flag-LDLR-transfected HEK293T cells were used for immunoprecipitation assays. Immunoprecipitates were washed, separated by SDS–polyacrylamide gel electrophoresis and immunoblotted as indicated.

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.
