TRUB2 Inhibitors

TRUB2 inhibitors are a class of chemical compounds designed to target and inhibit the activity of TRUB2, a member of the TruB family of pseudouridine synthases. TRUB2 is responsible for catalyzing the isomerization of uridine to pseudouridine in RNA molecules, particularly in transfer RNA (tRNA) and ribosomal RNA (rRNA). Pseudouridine plays a crucial role in stabilizing RNA structures, enhancing base-pairing interactions, and supporting the proper function of the translational machinery. By inhibiting TRUB2, these compounds disrupt the formation of pseudouridine, potentially affecting the stability and functionality of RNA molecules in processes like protein synthesis and RNA processing.

The mechanism of TRUB2 inhibitors typically involves binding to the active site of the enzyme, preventing it from catalyzing the conversion of uridine to pseudouridine. These inhibitors may also alter the enzyme's conformation, rendering it unable to interact with its RNA substrates. Researchers use TRUB2 inhibitors to investigate the role of pseudouridine in RNA structure and function, exploring how changes in RNA modification can influence cellular processes such as translation and RNA stability. By inhibiting TRUB2, scientists can gain insights into the molecular mechanisms of RNA modification and how disruptions in these processes impact cellular homeostasis and gene expression. These inhibitors provide valuable tools for studying the broader significance of RNA modifications in biology, particularly in understanding how pseudouridine contributes to the efficiency and accuracy of the cellular machinery responsible for protein synthesis and gene regulation.
