General Information | Comment | Organism |
---|---|---|
physiological function | MTAP substrates protect MTAP-positive cells from toxicity of adenine analogs 2,6-diaminopurine, 6-methylpurine, and 2-fluoroadenine and clinical cancer drugs 5-fluorouracil or 6-thioguanine. Adenine analog plus 5'-methylthioadenosine, kills MTAP-negative A549 lung tumor cells, while MTAP-positive human fibroblasts are protected, whereas in co-cultures of the breast tumor cell line, MCF-7, and HF cells, MCF-7 is inhibited or killed, while HF cells proliferate robustly | Homo sapiens |
