“…First, in the cytoplasm, SHMT1 and DHFR also participate in the folate cycle, whereas TYMS was shown to take part in mitochondrial de novo dTMP synthesis [ 6 ]; therefore, it is likely that formation of the dTMP‐SC complex may affect not only the dTMP pool, but also the whole one‐carbon metabolism. In addition, given that the complex certainly has a very different surface accessibility with respect to the single enzymes, it is probable that its assembly directly affects/controls other post‐transcriptional modifications, such as SUMOylation or the ability of these enzymes to bind RNA [ 27 , 44 , 45 , 46 ].…”
