MAT2A(甲硫氨酸腺苷转移酶2A),也称为AdoMet合成酶2,是甲硫氨酸循环中的限速酶,它催化甲硫氨酸与ATP生成S-腺苷甲硫氨酸(SAM)。它是S-腺苷甲硫氨酸合成酶复合物的催化亚基。SAM的水平对众多细胞过程至关重要,包括DNA、RNA和组蛋白的修饰。在肝脏中,MAT2A的表达与细胞生长、去分化及癌症发生相关。在去势抵抗性前列腺癌(CRPC)中,MAT2A通过促进促肿瘤性非经典雄激素受体(AR)靶基因的H3K4me2修饰,在维持癌症干细胞干性和肿瘤发生过程中发挥作用。MAT2A抑制剂与雄激素受体(AR)和zeste同源物增强子2(EZH2)抑制剂联合使用时,在去势抵抗性前列腺癌模型中展现出良好的应用前景。MAT2A是甲基硫腺苷磷酸化酶(MTAP)缺陷癌症的合成致死靶点,使其成为极具潜力的肿瘤治疗靶点。

Notes
Contraindications
• The final concentration of DMSO in the assay should not exceed 1%.
• Some compounds may interfere with the results, depending on their color, spectral excitation and emission properties.
• It is recommended that the compound alone is tested to determine any potential interference of the compound with the assay results.
• Colorimetric Detection Reagent is used to measure the free phosphate from the MAT2A reaction. Any source of inorganic phosphate can interfere with the assay.Warnings
Avoid freeze/thaw cycles.
