RNA-mediated modulation of cell metabolism

RNA-mediated modulation of cell metabolism

The perception of RNA–protein interactions is currently changing from a protein-centric approach, in which proteins regulate the expression and activity of RNA, to a more complex view, in which RNA molecules can directly regulate protein's function and thus cell behavior, in a process called riboregulation.

Differential inhibitory effect of a pyrazolopyran compound on human serine hydroxymethyltransferase-amino acid complexes

Serine hydroxymethyltransferase (SHMT) is a pivotal enzyme in one-carbon metabolism that catalyses the reversible conversion of serine and tetrahydrofolate into glycine and methylenetetrahydrofolate. It exists in cytosolic (SHMT1) and mitochondrial (SHMT2) isoforms. Research on one-carbon metabolism in cancer cell lines has shown that SHMT1 preferentially catalyses serine synthesis, whereas in mitochondria SHMT2 is involved in serine breakdown. Recent research has focused on the identification of inhibitors that bind at the folate pocket.
