The mRNA Poly(A)-Binding Protein: Localization, Abundance, and RNA-Binding Specificity
Experimental Cell Research, 1994 The poly(A)-binding protein (PABP) binds to the messenger (mRNA) 3'-poly(A) tail found on most eukaryotic mRNAs and together with the poly(A) tail has been implicated in governing the stability and the translation of mRNA. In order to further understand the role of the PABP in these processes, we have undertaken a detailed analysis of the cellular ...

Mammalian N1-adenosine PARylation is a reversible DNA modification
Nature Communications, 2022 Poly-ADP-ribosylation (PARylation) is a well-known posttranslational modification of proteins. Here the authors show that beyond proteins also mammalian single-stranded DNA is PARylated in vitro and in vivo.

Advanced Functional Materials, EarlyView.A shape‐memory microneedle system enables reproductive hormone therapy through a single transdermal insertion. The X‐shaped device sustains follicle‐stimulating hormone release for three days, and mild heating restores the O shape to trigger burst human chorionic gonadotropin release.

Paip1 Interacts with Poly(A) Binding Protein through Two Independent Binding Motifs [PDF]
Molecular and Cellular Biology, 2002 The 3' poly(A) tail of eukaryotic mRNAs plays an important role in the regulation of translation. The poly(A) binding protein (PABP) interacts with eukaryotic initiation factor 4G (eIF4G), a component of the eIF4F complex, which binds to the 5' cap structure.

Mechanical and Electrical Phenotype of hiPSC‐Cardiomyocytes on Fibronectin‐Based Hydrogels
Advanced Healthcare Materials, EarlyView.We introduce fibronectin‐based PEG hydrogels with controlled rigidity to enable the culture of iPSC‐derived cardiomyocytes. These substrates offer an alternative to the current culture of these cells on fibronectin‐coated glass, providing enhanced structural and functional behavior. The system provides a more physiologically relevant platform to assess

Eukaryotic initiation factor 4B and the poly(A)-binding protein bind eIF4G competitively [PDF]
Translation, 2013 The eukaryotic translation initiation factor (eIF) 4G functions as a scaffold protein that assembles components of the translation initiation complex required to recruit the 40S ribosomal subunit to an mRNA. Although many eukaryotes express two highly similar eIF4G isoforms, those in plants are highly divergent in size and sequence from one another and
