M6A-Seq in METTL14 R298P mutation knock-in cell clones
Ontology highlight
ABSTRACT: N6-methyladenosine (m6A) is the major type of RNA modification that regulates RNA stability and gene expression, characterized by a conserved motif including 5′-(m6A)C-3′. However, the functional significance of the specific motif for m6A modification is unclear. Here, we focused on a single amino acid substitution in the m6A “writer” complex, METTL14 R298P, and created mutation knock-in cells. m6A individual-nucleotide-resolution cross-linking and immunoprecipitation and methylated RNA immunoprecipitation with next-generation sequencing (MeRIP-Seq) revealed that METTL14R298P/R298P but not METTL14WT/R298P cells had an aberrant sequence motif, 5′-(m6A)[C/T]-3′. This study reveals a mechanism underlying sequence-specific m6A modification.
