The dihydrofolate reductase is a key enzyme of the folate metabolism which supplies the cell with dTTPs for DNA synthesis. Using cellular extracts, we demonstrate the formation of c-Myc/Max heterodimers at the dihydrofolate reductase (DHFR) 5' flanking CANNTG (E-box) motifs. The presence of these complexes correlates with c-Myc levels and active cellular proliferation.
二氢叶酸还原酶是叶酸代谢的关键酶,为细胞提供用于DNA合成的脱氧胸苷三磷酸(dTTPs)。利用细胞提取物,我们证明了在二氢叶酸还原酶(DHFR)5'侧翼的CANNTG(E盒)基序处形成了c-Myc/Max异源二聚体。这些复合物的存在与c-Myc水平和活跃的细胞增殖相关。
