MTAP encodes methylthioadenosine phosphorylase, an enzyme also called MTAPase. It catalyzes the breakdown of S-methyl-5'-thioadenosine (MTA) into adenine and 5-methylthio-D-ribose 1-phosphate, a key step in purine salvage metabolism. Loss of MTAP leads to MTA accumulation, activating the mTOR signaling pathway to promote cell proliferation.
MTAP deletion is frequent in glioblastoma, lung cancer, and melanoma, often co-occurring with CDKN2A loss on chromosome 9p21. Drug development targeting MTAP-deficient tumors is ongoing: mTOR inhibitors like everolimus show preclinical efficacy, while agents blocking MTA-mediated signaling are explored as potential therapies.

Immunofluorescence staining of Hela cell with CSB-RA299565A0HU at 1:50, counter-stained with DAPI. The cells were fixed in 4% formaldehyde, permeabilized using 0.2% Triton X-100 and blocked in 10% normal Goat Serum. The cells were then incubated with the antibody overnight at 4°C. The secondary antibody was Alexa Fluor 488-congugated AffiniPure Goat Anti-Rabbit IgG(H+L).
Overlay Peak curve showing Hela cells stained with CSB-RA299565A0HU (red line) at 1:100. The cells were fixed in 4% formaldehyde and permeated by 0.2% TritonX-100 for 10min. Then 10% normal goat serum to block non-specific protein-protein interactions followed by the antibody (1ug/1*106cells) for 45min at 4℃. The secondary antibody used was FITC-conjugated goat anti-rabbit IgG (H+L) at 1/200 dilution for 35min at 4℃.Control antibody (green line) was Rabbit IgG (1ug/1*106cells) used under the same conditions. Acquisition of >10,000 events was performed.
