Target data

Function

Involved in the cellular defense against the biological effects of O6-methylguanine (O6-MeG) and O4-methylthymine (O4-MeT) in DNA. Repairs the methylated nucleobase in DNA by stoichiometrically transferring the methyl group to a cysteine residue in the enzyme. This is a suicide reaction: the enzyme is irreversibly inactivated.

Notes

ab233012 is the carrier-free version of Anti-MGMT antibody [EPR4397] ab108630.

Our RabMAb® technology is a patented hybridoma-based technology for making rabbit monoclonal antibodies. For details on our patents, please refer to RabMAb® patents.

This product is a recombinant monoclonal antibody, which offers several advantages including:

  • - High batch-to-batch consistency and reproducibility
  • - Improved sensitivity and specificity
  • - Long-term security of supply
  • - Animal-free batch production

For more information, read more on recombinant antibodies.

Our carrier-free antibodies are typically supplied in a PBS-only formulation, purified and free of BSA, sodium azide and glycerol. The carrier-free buffer and high concentration allow for increased conjugation efficiency.

This conjugation-ready format is designed for use with fluorochromes, metal isotopes, oligonucleotides, and enzymes, which makes them ideal for antibody labelling, functional and cell-based assays, flow-based assays (e.g. mass cytometry) and Multiplex Imaging applications.

Use our conjugation kits for antibody conjugates that are ready-to-use in as little as 20 minutes with 1 minute hands-on-time and 100% antibody recovery: available for fluorescent dyes, HRP, biotin and gold.

This product is compatible with the Maxpar® Antibody Labeling Kit from Fluidigm, without the need for antibody preparation. Maxpar® is a trademark of Fluidigm Canada Inc.

Activity summary

MGMT also known as O-6-methylguanine-DNA methyltransferase is an enzyme with a significant role in DNA repair. MGMT protein has a molecular weight of about 22 kDa. This protein is typically expressed in various tissues including the liver kidney and brain where it functions to protect cells from mutagenic and cytotoxic alterations. MGMT works by transferring alkyl groups from the O6 position of guanine to a cysteine residue within its active site. This mechanism directly reverses DNA damage maintaining genomic stability.

Biological function summary

MGMT prevents mutations by reversing alkylation damage playing a significant role in preserving DNA integrity. It acts independently and does not form part of any larger protein complexes. This enzyme-mediated repair is central to cellular defense against mutagenic threats such as alkylating agents. By curbing DNA damage MGMT can thwart the onset of harmful genetic mutations that might lead to issues like cancer development.

Pathways

MGMT is intimately involved in DNA damage response and repair pathways. Notably it interacts with base excision repair and direct reversal repair pathways. MGMT's function is distinct but complementary to the activities of other DNA repair proteins like XRCC1 and APE1 which are involved in the base excision repair pathway. The presence of MGMT bolsters cellular resilience by ensuring that DNA lesions caused by alkylating agents are addressed promptly and effectively.

Associated diseases and disorders

MGMT has a profound association with several types of cancer such as glioblastoma and colorectal cancer. Reduced MGMT expression or activity can lead to enhanced susceptibility to the carcinogenic effects of alkylating agents making cancer development more likely. Additionally MGMT inhibitors such as lomeguatrib are used therapeutically to enhance the effectiveness of alkylating chemotherapy. Within this context MGMT interacts with proteins involved in tumor suppression and cell cycle regulation including p53 influencing both cancer progression and treatment outcomes.

    Anti-MGMT antibody [EPR4397] ab108630 was shown to specifically react with MGMT when MGMT knockout samples were used. Wild-type and MGMT knockout samples were subjected to SDS-PAGE. Anti-MGMT antibody [EPR4397] ab108630 and Anti-GAPDH antibody [6C5] - Loading Control ab8245 (loading control to GAPDH) were diluted 1/1000 and 1/2000 respectively and incubated overnight at 4°C.

    Western blot: Anti-MGMT antibody [EPR4397] (Anti-MGMT antibody [EPR4397] ab108630) staining at 1/1000 dilution, shown in green; Mouse anti-Alpha Tubulin [DM1A] (Anti-alpha Tubulin antibody [DM1A] - Loading Control ab7291) loading control staining at 1/20000 dilution, shown in magenta. In Western blot, Anti-MGMT antibody [EPR4397] ab108630 was shown to bind specifically to MGMT. A band was observed at 22 kDa in wild-type HCT 116 cell lysates with no signal observed at this size in MGMT CRISPR-Cas9 edited cell line Human MGMT knockout HCT116 cell line ab286541. The band observed in the CRISPR-Cas9 edited lysate lane below 22 kDa is likely to represent a truncated form of MGMT. This has not been investigated further and the functional properties of the gene product have not been determined. To generate this image, wild-type and MGMT CRISPR-Cas9 edited HCT 116 cell lysates were analysed. First, samples were run on an SDS-PAGE gel then transferred onto a nitrocellulose membrane. Membranes were blocked in 3 % milk in TBS-0.1 % Tween® 20 (TBS-T) before incubation with primary antibodies overnight at 4 °C. Blots were washed four times in TBS-T, incubated with secondary antibodies for 1 h at room temperature, washed again four times then imaged. Secondary antibodies used were Goat anti-Rabbit IgG H&L 800CW and Goat anti-Mouse IgG H&L 680RD at 1/20000 dilution.
