METTL1 Inhibitors

METTL1 inhibitors represent a chemical class of compounds specifically designed to target and inhibit the activity of METTL1, a key enzyme involved in the process of methylating guanosine (G) residues at the N7 position (m7G) in transfer RNAs (tRNAs). METTL1, also known as tRNA (m7G46) methyltransferase, plays a crucial role in post-transcriptional modifications of tRNAs, which are essential for maintaining accurate translation during protein synthesis. These inhibitors are primarily developed for research purposes to better understand the biological functions of METTL1 and its impact on gene expression regulation. The mechanism of action of METTL1 inhibitors typically involves disrupting the enzyme's catalytic activity by interfering with its binding to essential cofactors, such as S-adenosylmethionine (SAM). Many METTL1 inhibitors act as competitive inhibitors of SAM, effectively competing with SAM for binding to METTL1's active site. By binding to METTL1 and blocking SAM access, these inhibitors prevent the enzyme from catalyzing the methylation of m7G in tRNAs. Consequently, this disruption in the methylation process can have downstream effects on translation, influencing the fidelity and efficiency of protein synthesis. METTL1 inhibitors are valuable tools in the field of molecular biology and cellular research, as they allow scientists to modulate METTL1 activity in a controlled manner, enabling the investigation of its precise roles in cellular processes and its impact on gene expression without the need for genetic manipulation.
