m1A and m6A modifications function cooperatively to facilitate rapid mRNA degradation

open access: yesCell Reports, 2022
N6-Methyladenosine (m6A), the most abundant internal mRNA modification, affects multiple steps in gene expression. Mechanistically, the binding of YTHDF2 to m6A on mRNAs elicits rapid mRNA degradation by recruiting several RNA degrading enzymes. Here, we show that N1-methyladenosine (m1A), another type of RNA modification, accelerates rapid m6A RNA ...

Cytoplasmic m1A reader YTHDF3 inhibits trophoblast invasion by downregulation of m1A-methylated IGF1R [PDF]

open access: yesCell Discovery, 2020
AbstractN1-methyladenosine (m1A) is one of the important post-transcriptional modifications in RNA and plays an important role in promoting translation or decay of m1A-methylated messenger RNA (mRNA), but the “reader” protein and the exact biological role of m1A remain to be determined.

Dysregulation of the Epitranscriptomic Mark m1A in Ischemic Stroke

Translational Stroke Research, 2022
Methylation of adenosine at N1 position yields N1-methyladenosine (m1A), which is an epitranscriptomic modification that regulates mRNA metabolism. Recent studies showed that altered m1A methylation promotes acute and chronic neurological diseases. We currently evaluated the effect of focal ischemia on cerebral m1A methylome and its machinery.

Mo’ m1A, mo’ problems

Cell Chemical Biology
CAG-repeat expansions underlie fatal neurodegenerative disorders. In a lodestar study published in a recent issue of Nature, Sun et al.1 identify a writer and eraser of N1-methyladenosine (m1A) modifications of CAG-repeat RNA. They establish that m1A modifications in CAG-repeat expanded RNA promote neurodegeneration and aberrant phase transitions of ...

The m1A landscape on cytosolic and mitochondrial mRNA at single-base resolution

Nature, 2017
Modifications on mRNA offer the potential of regulating mRNA fate post-transcriptionally. Recent studies suggested the widespread presence of N1-methyladenosine (m1A), which disrupts Watson-Crick base pairing, at internal sites of mRNAs. These studies lacked the resolution of identifying individual modified bases, and did not identify specific sequence
