Conserved amino acid networks modulate discrete functional properties in an enzyme superfamily

Scientific Reports, 2017
In this work, we applied the sequence-based statistical coupling analysis approach to characterize conserved amino acid networks important for biochemical function in the pancreatic-type ribonuclease (ptRNase) superfamily.

Ribonuclease (RNase) Prolongs Survival of Grafts in Experimental Heart Transplantation

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2016
BackgroundCell damage, tissue and vascular injury are associated with the exposure and release of intracellular components such as RNA, which promote inflammatory reactions and thrombosis. Based on the counteracting anti‐inflammatory and cardioprotective

Possible role of human ribonuclease dicer in the regulation of R loops

FEBS Open Bio, EarlyView.
R loops play an important role in regulating key cellular processes such as replication, transcription, centromere stabilization, or control of telomere length. However, the unscheduled accumulation of R loops can cause many diseases, including cancer, and neurodegenerative or inflammatory disorders. Interestingly, accumulating data indicate a possible

A rat pancreatic ribonuclease fused to a late cotton pollen promoter severely reduces pollen viability in tobacco plants

Genetics and Molecular Biology, 2000
The effects of an animal RNase fused to the late cotton pollen-specific promoter G9 in a plant system were investigated. Expression of the chimeric genes G9-uidA and G9-RNase in tobacco plants showed that the 1.2-kb promoter fragment of the G9 gene was ...

Synthetic Strategy for mRNA Encapsulation and Gene Delivery with Nanoscale Metal‐Organic Frameworks

Advanced Functional Materials, EarlyView.
This research utilizes the ZIF‐8 for the encapsulation and intracellular delivery of nucleic acids, specifically mRNA, for applications in gene delivery. Integrating PEI addresses the issue of mRNA leakage from ZIF‐8, resulting in the delivery and expression of green fluorescent protein (GFP) in vitro and firefly luciferase in vivo.

IncRNA‐ZFAS1, an Emerging Gate‐Keeper in DNA Damage‐Dependent Transcriptional Regulation

Advanced Science, EarlyView.
LncZFAS1 plays a crucial role during DNA damage response in mammalian cells. Loss of lncZFAS1 results in deficient DNA lesion removal and reduced cell viability. Mechanistically, lncZFAS1 modulates RNAPII phosphorylation and transcription and thereby promotes both GG‐NER and TC‐NER upon UV damage.

Comparison of the structure of turtle pancreatic ribonuclease with those of mammalian ribonucleases [PDF]

FEBS Letters, 1986
There are 33 invariant amino acid positions out of 132 positions in 42 investigated sequences of ribonucleases from a number of mammalian species and a reptile (snapping turtle, Chelydra serpentina). These invariant residues are unequally distributed over 3 different parts of the molecule. The lobe of the S‐protein part of the molecule, which lacks one

Human pancreatic ribonuclease: deletion of the carboxyl-terminal EDST extension enhances ribonuclease activity and thermostability [PDF]

, 1997
Mammalian ribonucleases constitute one of the fastest evolving protein families in nature. The addition of a four-residue carboxyl-terminal tail: Glu-Asp-Ser-Thr (EDST) in human pancreatic ribonuclease (HPR) in comparison with bovine pancreatic RNase ...
