Structural insight into precursor ribosomal RNA processing by ribonuclease MRP
Adapted to the task at hand RNA-based catalysts perform fundamental tasks in cellular RNA metabolism, especially in eukaryotes, where RNAs are cut by specialized ribonucleoproteins (RNPs) as part of ribosome assembly or messenger RNA regulation or ...

Human and mouse angiogenins: Emerging insights and potential opportunities
Angiogenin, a well-known angiogenic factor, is crucial to the angiogenesis in gastrointestinal tumors. Human angiogenin has only one gene, whereas the murine angiogenin family has extended to incorporate six genes.

The compactness of ribonuclease A and reduced ribonuclease A
The compactness of ribonuclease A with intact disulfide bonds and reduced ribonuclease A was investigated by synchrotron small‐angle X‐ray scattering. The R g values and the Kratky plots showed that non‐reduced ribonuclease A maintain a compact shape with a R g value of about 17.3 Å in 8 M urea.

The S-peptide and S-protein components of bovine pancreatic ribonuclease form a noncovalent complex with restored ribonucleolytic activity. Although this archetypal protein-fragment complementation system has been the object of historic work in protein chemistry, intrinsic limitations compromise its utility.

An ancient evolutionary connection between Ribonuclease A and EndoU families
The ribonuclease A family of proteins is well studied from the biochemical and biophysical points of view, but its evolutionary origins are obscure, as no sequences homologous to this family have been reported outside of vertebrates.

Ribonucleases as potential therapeutic agents [PDF]
Objective Due to high cytotoxicity effect, ribonucleases (RNases) are known as pharmacological agents with therapeutic potential. The high potential of these enzymes in the destruction of RNA strand and their other substrates and subsequently, cell ...

Mammalian mitochondrial RNAs are degraded in the mitochondrial intermembrane space by RNASET2
Mammalian mitochondrial genome encodes a small set of tRNAs, rRNAs, and mRNAs. The RNA synthesis process has been well characterized. How the RNAs are degraded, however, is poorly understood. It was long assumed that the degradation happens in the matrix

Inhibition of IRE1α-mediated XBP1 mRNA cleavage by XBP1 reveals a novel regulatory process during the unfolded protein response [PDF]
Background: The mammalian endoplasmic reticulum (ER) continuously adapts to the cellular secretory load by the activation of an unfolded protein response (UPR).

Histone deacetylase 2-mediated deacetylation of the Ribonuclease 1 promoter in inflamed human endothelial cells [PDF]
Endothelial cells (ECs) function as protective barrier to separate the blood from the surrounding tissue by conducting crucial roles in regulation and maintenance of vascular homeostasis, such as control of vessel permeability or coagulation.
