Western blot - Anti-MGMT antibody [MT3.1] (AB39253)

Western blot : Anti-MGMT antibody [MT3.1] (ab39253) staining at 1/500 dilution, shown in green; Rabbit anti-alpha Tubulin antibody [EP1332Y] (ab52866) loading control staining at 1/20000 dilution, shown in magenta. In Western blot, ab39253 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 knockout cell line ab286541. The band observed in the knockout 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 knockout 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-Mouse IgG H&L 800CW and Goat anti-Rabbit IgG H&L 680RD at 1/20000 dilution.

Supplementary information

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.

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.

Target data

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.
