Recombinant Human CUE domain-containing protein 2 (CUEDC2)

Uniprot Id

Q9H467

Target Species

Human

Target Name

CUEDC2

Target Full Name

CUE domain-containing protein 2

Target Function

Down-regulates ESR1 protein levels through the ubiquitination-proteasome pathway, regardless of the presence of 17 beta-estradiol. Also involved in 17 beta-estradiol-induced ESR1 degradation. Controls PGR protein levels through a similar mechanism.

Target Involvement

May predict the clinical outcome of tamoxifen therapy of breast cancer patients. Patients with tumors that highly express CUEDC2 do not respond to tamoxifen treatment as effectively as those with tumors with low expression.

Target Subcellular Location

Cytoplasm. Nucleus.

Target Protein Families

CUEDC2 family

Target Tissue Specificity

Significantly up-regulated in breast tumor tissues compared with matched adjacent normal tissues (at protein level). Levels inversely correlate with ESR1 in breast cancers and are lower in low-grade tumors compared to high-grade tumors.

Target Research Area

Epigenetics and Nuclear Signaling

Target Synonyms

bA18I14.5; C10orf66; Chromosome 10 open reading frame 66 ; CUE domain containing 2; CUE domain-containing protein 2; CUED2; CUED2_HUMAN; Cuedc2; MGC2491; OTTHUMP00000020368

Target Background

Predicted to enable ubiquitin binding activity. Acts upstream of or within negative regulation of cytokine production involved in inflammatory response and negative regulation of macrophage cytokine production. Located in cytosol; nuclear membrane; and nucleoplasm.
