Monoclonal Antibody to MBD1 (Clone: ABM15H2) FITC Conjugated

MBD1 (Methyl-CpG-Binding Domain Protein 1) protein is a primary candidate for the readout of DNA methylation as it recruits chromatin remodelers, histone deacetylases and methylases to methylated DNA associated with gene repression. This protein, a member of a transcriptional repressor family MBD, is predominantly expressed in neurons. MBD protein binding requires both functional MBD domains and methyl-CpGs; however, some MBD proteins also bind unmethylated DNA and active regulatory regions via alternative regulatory domains or interaction with the NuRD/Mi-2 (Nucleosome Remodeling Deacetylase) complex members. The CXXC3 domain of MBD1 makes it a unique member of the MBD family due to its affinity to unmethylated DNA. MBD1 acts as an epigenetic regulator via different mechanisms, such as the formation of the MCAF1/MBD1/SETDB1 complex or the MBD1-HDAC3 complex. It also plays an important role in disease progression, contributes to the drug resistance of PC cells; however, the mechanism underlying the drug resistance endowed by MBD1 remains unknown.
