Human CpG binding protein (hCGBP) contains three cysteine-rich domains, two of which exhibit homology to the plant homeodomain finger domain and the third cysteine-rich domain conforms to the CXXC motif identified in DNA methyltransferase, human trithorax, and methyl-CpG binding domain protein 1. A fragment of hCGBP that contains the CXXC domain binds to an oligonucleotide probe containing a single CpG site, and this complex is disrupted by distinct oligonucleotide competitors that also contain a CpG motif(s). CBGP plays an important part in embryonic viability and peri-implantation development. Native hCGBP is detected as an 88kD protein by Western analysis and is ubiquitously expressed. CGBP trans-activates promoters that contain CpG motifs but not promoters in which the CpG is ablated suggesting that hCGBP is a transcriptional activator that recognizes unmethylated CpG dinucleotides. Applications: Suitable for use in Western Blot. Other applications not tested. Recommended Dilution: Western Blot: 1:1000 Optimal dilutions to be determined by the researcher. Positive Control: Human spleen Storage and Stability: May be stored at 4 degrees C for short-term only. Aliquot to avoid repeated freezing and thawing. Store at -20 degrees C. Aliquots are stable for at least 12 months. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
