Detection of Human and Mouse MBD4 by Western Blot. Western blot shows lysates of HepG2 human hepatocellular carcinoma cell line, Raji human Burkitt's lymphoma cell line, and C2C12 mouse myoblast cell line. PVDF membrane was probed with 1 µg/mL of Goat Anti-Human/Mouse MBD4 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF5935) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF019). A specific band was detected for MBD4 at approximately 68 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Background: MBD4

MBD4 (Methyl CpG-binding domain protein 4; also MED1) is a 65-68 kDa member of the methyl CpG binding protein family. It is expressed in non-germline cells, and serves at least two functions: one, it interacts with FADD to up- or down-regulate apoptosis, and two, it acts as a DNA N-glycosylase that excises improper chromosomal thymines that are created through the spontaneous deamination of methylcytosine to thymine. Human MDB4 is 580 amino acids (aa) in length. It contains one DNA-binding MBD domain (aa 76-148) and one endonuclease domain (aa 455-580). There are three isoform variants. One shows a deletion of aa 395-400, another shows an AlaPro substitution for aa 539-580, and a third shows a Gln substitution for aa 83-401. Over aa 382-580, human MBD4 shares 90% aa identity with mouse MBD4.
