Description

General description

Anti-MBD2a,b (RA-18) is developed in rabbit using as immunogen a synthetic peptide corresponding human MBD2a conjugated to KLH. MBD2 consists of two isoforms, MBD2a and MBD2b, which are generated from a single gene; MBD2a is a 414 amino acids protein, whereas MBD2b lacks the 152 amino acids N-terminal extension. MBD2a is a component of the MeCP1 corepressor complex, which is a 400-800 kDa complex containing as components MBD2, Mi-2, MTA2, MBD3, and HDAC1/2.

The gene encoding methyl-CpG binding domain protein 2 (MBD2a) is localized on chromosome 18.

Specificity

The antibody recognizes MBD2a (~45 kDa) and MBD2b (~29 kDa). In immunoblotting, an unidentified band at ~43 kDa may also be detected.

Immunogen

synthetic peptide corresponding to amino acids 294-411 of human MBD2a conjugated to KLH via an N-terminal added lysine residue. This sequence is conserved in MBD2a and MBD2b of human origin, and is not found in MBD3.

Application

Anti-MBD2a,b (RA-18) antibody produced in rabbit has been used:

• for chromatin immunoprecipitation and western blotting
• immunofluorescence
• immunoblotting

Biochem/physiol Actions

MBD2 binds to methylated DNA in vitro or in vivo, suggesting that MBD2 targets the MeCP1 complex to methylated DNA. MBD2a interacts with RNA Helicase A (RHA). MBD2 protein appear to protect against some cancers.

Methyl-CpG binding domain protein 2 (MBD2a) acts as a repressor during transcription.

Physical form

Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 15 mM sodium azide.
