PEP-130 is a 13 amino acid synthetic peptide whose sequences are derived from human MBD1 protein. The sequence of this peptide is (amino to carboxy terminus): C-R (593)-S-K-D-L-K-K-P-G-A-R-K-Q (605)
This peptide may be used for neutralization and control experiments with the polyclonal antibody that reacts with this product and human MBD1, catalog # PA1-889. Using a solution of peptide of equal volume and concentration to the corresponding antibody will yield a large molar excess of peptide (~70-fold) for competitive inhibition of antibody-protein binding reactions.
Reconstitute with 0.1 mL of distilled water.
Methyl-CpG-binding domain protein 1 (MBD1) is a member of a family of mammalian proteins that specifically bind methylated regions of DNA. It is a transcriptional repressor that binds CpG islands in promoters where the DNA is methylated at position 5 of cytosine within CpG dinucleotides. Binding is abolished by the presence of 7-mG that is produced by DNA damage by methylmethanesulfonate (MMS). MBD1 acts as a transcriptional repressor and plays a role in gene silencing by recruiting AFT7IP, which in turn recruits factors such as the histone methyltransferase SETDB1. Isoform 1 and isoform 2 can also repress transcription from unmethylated promoters.
