Anti-CUEDC2 Antibody Picoband®

CUEDC2 (Cue Domain-Containing Protein 2) is involved in ubiquitin-and proteasome-mediated degradation of progesterone receptor (PR, or PGR) and estrogen receptor (ER) -alpha. Hartz (2011) mapped the CUEDC2 gene to chromosome 10q24.32 based on an alignment of the CUEDC2 sequence with the genomic sequence (GRCh37) . Using coimmunoprecipitation analysis and protein pull-down assays, Zhang et al. (2007) confirmed that CUEDC2 interacted with the PRB isoform of PR. Mutation analysis revealed that the IF domain of PRB and the CUE domain of CUEDC2 were required for the interaction. CUEDC2 reduced PRB protein content and promoted progesterone-induced PRB degradation via the ubiquitin-proteasome pathway.

No cross-reactivity with other proteins

A synthetic peptide corresponding to a sequence at the C-terminus of human CUEDC2, identical to the related mouse sequence, and different from the related rat sequence by one amino acid.

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.
