Biochemical characterization and three-dimensional structure analysis of the yeast cleavage and polyadenylation factor CPF [PDF]

open access: yes, 2008
In eukaryotes, protein-encoding genes are transcribed in the nucleus by RNA polymerase II (RNAP II). Before the gene transcript (pre-mRNA) is transported to the cytoplasm and can function in translation, it has to undergo three specific maturation ...

Detection of Differentially Expressed Cleavage Site Intervals Within 3′ Untranslated Regions Using CSI-UTR Reveals Regulated Interaction Motifs

open access: yesFrontiers in Genetics, 2019
The length of untranslated regions at the 3′ end of transcripts (3′UTRs) is regulated by alternate polyadenylation (APA). 3′UTRs contain regions that harbor binding motifs for regulatory molecules. However, the mechanisms that coordinate the 3′UTR length

Characterization of factors involved in the coupling of 3' end processing and splicing and in the 3' end formation of mRNA precursors [PDF]

open access: yes, 2006
Eukaryotic mRNA precursors are processed at their 5’ and 3’ ends and are spliced prior to their export from the nucleus to the cytoplasm. Although all three processing reactions can be studied separately in vitro, they are coupled in vivo.

Overexpression of CPEB4 in glioma indicates a poor prognosis by promoting cell migration and invasion

open access: yesTumor Biology, 2017
Glioma is an aggressive malignancy with limited effective treatment and poor prognosis. Cytoplasmic polyadenylation element binding protein 4 is a regulator of gene transcription and has been reported to be associated with biological malignancy in ...

Analysis of Polyadenylation Signal Usage with Full-Length Transcriptome in Spodoptera frugiperda (Lepidoptera: Noctuidae)

open access: yesInsects, 2022
During the messenger RNA (mRNA) maturation process, RNA polyadenylation is a key step, and is coupled to the termination of transcription. Various cis-acting elements near the cleavage site and their binding factors would affect the process of ...

A new yeast poly(A) polymerase complex involved in RNA quality control [PDF]

open access: yes, 2005
Eukaryotic cells contain several unconventional poly(A) polymerases in addition to the canonical enzymes responsible for the synthesis of poly(A) tails of nuclear messenger RNA precursors.

RNA binding protein Caprin-2 is a pivotal regulator of the central osmotic defense response

open access: yeseLife, 2015
In response to an osmotic challenge, the synthesis of the antidiuretic hormone arginine vasopressin (AVP) increases in the hypothalamus, and this is accompanied by extension of the 3′ poly(A) tail of the AVP mRNA, and the up-regulation of the expression ...

Regulation of Germ Cell mRNPs by eIF4E:4EIP Complexes: Multiple Mechanisms, One Goal

open access: yesFrontiers in Cell and Developmental Biology, 2020
Translational regulation of mRNAs is critically important for proper gene expression in germ cells, gametes, and embryos. The ability of the nucleus to control gene expression in these systems may be limited due to spatial or temporal constraints, as ...

Birth of a poly(A) tail: mechanisms and control of mRNA polyadenylation

open access: yesFEBS Open Bio, 2023
During their synthesis in the cell nucleus, most eukaryotic mRNAs undergo a two‐step 3′‐end processing reaction in which the pre‐mRNA is cleaved and released from the transcribing RNA polymerase II and a polyadenosine (poly(A)) tail is added to the newly

PAPD5, a noncanonical poly(A) polymerase with an unusual RNA-binding motif [PDF]

open access: yes, 2011
PAPD5 is one of the seven members of the family of noncanonical poly(A) polymerases in human cells. PAPD5 was shown to polyadenylate aberrant pre-ribosomal RNAs in vivo, similar to degradation-mediating polyadenylation by the noncanonical poly(A ...
