LRP2 and Ataxia: As the earliest identified component of m6A methyltransferase-possessing methylation catalysts, METTL3 plays a role in neural development, and its absence causes hypoplasia of the cerebellum in mice, resulting in ataxia.355 METTL3 catalyzes the m6A modification of the low-density lipoprotein receptor-related protein 2 (LRP2) mRNA to improve its stability and efficiency in translation.
