we show that poly(A) tail length and internal non-A residues are highly dynamic during the human OET, using poly(A)-inclusive RNA isoform sequencing (PAIso-seq). Unexpectedly, maternal
Here we have mapped the 3'-termini of mature mitochondrial mRNAs in three tissues (skeletal muscle, heart, and liver) from a healthy individual and an LSFC patient. We show that the poly (A) tail length of mitochondrial mRNAs varies amongst tissues, and that the missense mutation in LRPPRC...
Previously, we made mice possessing a mutation causing FNDI and reported that the mice manifested progressive polyuria as do the patients with FNDI. Here, we report that decreases in AVP mRNA expression in the supraoptic nucleus were accompanied by shortening of the AVP mRNA poly(A) tail ...
The polyadenosine tail (poly[A]-tail) is a universal modification of eukaryotic messenger RNAs (mRNAs) and non-coding RNAs (ncRNAs). In budding yeast, Pap1-synthesized mRNA poly(A) tails enhance export and translation, whereas Trf4/5-mediated polyadenyla

The poly(A)-limiting element (PLE) restricts the length of the poly(A) tail to G mutation following the AG dinucleotide in the PLE resulted in mRNA with poly(A) ranging from 25-50 nt. This reverted to a discrete, <20 nt poly(A) tail in cells expressing U2AF65. Our results suggest...

Mutation of any of these four amino acids substantially reduces the overall enzymatic activity of PARN. PARN exists as a dimer with the exonuclease domain acting to coordinate the two subunits [16]. The dimeric structure of PARN has been determined by X-ray crystallography of partial prote...
Most eukaryotic mRNAs are subject to considerable post-transcriptional modification, including capping, splicing, and polyadenylation. The process of polyadenylation adds a 3' poly(A) tail and provides the mRNA with a binding site for a major class of re
transcript, PAPα adds a poly(A) tail to the upstream fragment of cleaved RNA. The nuclear poly(A) binding protein (PABPN1) binds the nascent poly(A) tail, confers processivity to PAP and controls poly(A) tail length. PABPN1 also interacts with PAPα and CF I m and enhances the...
