Abstract

•METTL1-mediated m7G modification is crucial for various biological processes, including RNA stability, maturation and translation.

•METTL1 has emerged as a critical epigenetic modulator in human illnesses, with its dysregulated expression correlating with multiple diseases progression and presenting opportunities for both diagnostic biomarker development and molecular-targeted therapy.

•Enormous knowledge gaps persist regarding context-dependent regulatory networks of METTL1 and dynamic m7G modification patterns, necessitating mechanistic interrogation to bridge basic research with clinical translation in precision medicine.
