Fip1 is a multivalent interaction scaffold for processing factors in human mRNA 3′ end biogenesis
eLife, 2022 3′ end formation of most eukaryotic mRNAs is dependent on the assembly of a ~1.5 MDa multiprotein complex, that catalyzes the coupled reaction of pre-mRNA cleavage and polyadenylation. In mammals, the cleavage and polyadenylation specificity factor (CPSF)

Different 3' end regions strongly influence the level of gene expression in plant cells [PDF]
, 1989 We have investigated the functional role of a 3' end region on the expression of a reporter gene in plant cells. In stably transformed plants, expression of the reporter gene without a plant gene 3' end is variable and depends on the fortuitous presence ...

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

A snoRNA modulates mRNA 3' end processing and regulates the expression of a subset of mRNAs. [PDF]
, 2017 mRNA 3' end processing is an essential step in gene expression. It is well established that canonical eukaryotic pre-mRNA 3' processing is carried out within a macromolecular machinery consisting of dozens of trans-acting proteins. However, it is unknown

Sequence Determinants for Nuclear Retention and Cytoplasmic Export of mRNAs and lncRNAs
Frontiers in Genetics, 2018 Eukaryotes are divided into two major compartments: the nucleus where RNA is synthesized and processed, and the cytoplasm, where mRNA is translated into proteins.

Glutathione reductase-catalyzed cascade of redox reactions to bioactivate potent antimalarial 1,4-naphthoquinones--a new strategy to combat malarial parasites. [PDF]
, 2011 Our work on targeting redox equilibria of malarial parasites propagating in red blood cells has led to the selection of six 1,4-naphthoquinones, which are active at nanomolar concentrations against the human pathogen Plasmodium falciparum in culture and ...

RNA Binding Proteins that Control Human Papillomavirus Gene Expression
Biomolecules, 2015 The human papillomavirus (HPV) life cycle is strictly linked to the differentiation program of the infected mucosal epithelial cell. In the basal and lower levels of the epithelium, early genes coding for pro-mitotic proteins and viral replication ...

The transcriptional elongation rate regulates alternative polyadenylation in yeast
eLife, 2020 Yeast cells undergoing the diauxic response show a striking upstream shift in poly(A) site utilization, with increased use of ORF-proximal poly(A) sites resulting in shorter 3’ mRNA isoforms for most genes.

Bacterial/archaeal/organellar polyadenylation [PDF]
WIREs RNA, 2010 AbstractAlthough the first poly(A) polymerase (PAP) was discovered in Escherichia coli in 1962, the study of polyadenylation in bacteria was largely ignored for the next 30 years. However, with the identification of the structural gene for E. coli PAP I in 1992, it became possible to analyze polyadenylation using both biochemical and genetic approaches.

Plant polyadenylation factors: conservation and variety in the polyadenylation complex in plants
BMC Genomics, 2012 Background Polyadenylation, an essential step in eukaryotic gene expression, requires both cis-elements and a plethora of trans-acting polyadenylation factors. The polyadenylation factors are largely conserved across mammals and fungi.
