The Coup-TFII orphan nuclear receptor is an activator of the γ-globin gene

Haematologica, 2020
The human fetal γ-globin gene is repressed in the adult stage through complex regulatory mechanisms involving transcription factors and epigenetic modifiers.

PCA‐Based Database Mining Enables the Discovery of Bacterial Carbene Transferases for Stereodivergent Cyclopropanation

Angewandte Chemie, EarlyView.
Database mining using principal component analysis (PCA)‐based clustering enabled discovery of bacterial enzymes capable of catalyzing stereodivergent cyclopropanation of styrene. Statistical analyses of sequence data further revealed characteristic structural properties of these enzymes, highlighting the potential of the bioinformatics tools for ...

An Interplay of Gases: Oxygen and Hydrogen in Biological Systems

Oxygen
Produced by photosynthesis, oxygen (O2) is a fundamentally important gas in biological systems, playing roles as a terminal electron receptor in respiration and in host defence through the creation of reactive oxygen species (ROS).

TMC4 localizes to multiple taste cell types in the mouse taste papillae

FEBS Open Bio, EarlyView.
Transmembrane channel‐like 4 (TMC4), a voltage‐dependent chloride channel, plays a critical role in amiloride‐insensitive salty taste transduction. TMC4 is broadly expressed in all mature taste cell types, suggesting a possible involvement of multiple cell types in this pathway.

Globin-based redox signaling [PDF]

Worm, 2016
In recent years, moderate levels of reactive oxygen species (ROS) have become recognized as signaling cues that participate at all levels of cellular organization. Globins, with their redox-active heme iron and ubiquitous presence, seem ideally suited to participate in ROS metabolism.

Metallofullerenol Sc3N@C80(OH)18: A New Generation Radioprotector Protecting Human Erythrocytes Against Multiple Biochemical Damage Modes Upon Gamma Irradiation, Identifying It as a Scavenger of Short‐ and Long‐Lived Radicals

Advanced Healthcare Materials, EarlyView.
Metallofullerenol Sc3N@C80(OH)18 demonstrates strong radioprotective properties as a scavenger of both short‐ and long‐lived radicals. The study reveals protection of human erythrocytes from γ‐radiation–induced biochemical damage via post‐irradiation removal of primary and secondary reactive oxidants, supported by pulse radiolysis kinetics.

Testes-specific hemoglobins in Drosophila evolved by a combination of sub- and neofunctionalization after gene duplication

BMC Evolutionary Biology, 2012
Background For a long time the presence of respiratory proteins in most insects has been considered unnecessary. However, in recent years it has become evident that globins belong to the standard repertoire of the insect genome.

Biophysical characterisation of neuroglobin of the icefish, a natural knockout for hemoglobin and myoglobin. Comparison with human neuroglobin. [PDF]

PLoS ONE, 2012
The Antarctic icefish Chaenocephalus aceratus lacks the globins common to most vertebrates, hemoglobin and myoglobin, but has retained neuroglobin in the brain. This conserved globin has been cloned, over-expressed and purified. To highlight similarities

Cotranslational Folding of Globin [PDF]

Journal of Biological Chemistry, 1997
Globin synthesis in a wheat germ cell-free translation system was performed in the presence of [3H]hemin and [35S]methionine to determine the minimal length of the nascent ribosome-bound globin chain capable of heme binding. Nascent polypeptides of predetermined size were synthesized on ribosomes by translation of truncated mRNA molecules.

High‐Throughput In Vivo Screening Using Barcoded mRNA Identifies Lipid Nanoparticles With Extrahepatic Tropism for In Situ Immunoengineering

Advanced Materials, EarlyView.
A high‐throughput in vivo mRNA LNP screening platform is developed and employed to screen a large library of 122 mRNA LNPs in vivo for delivery to immune, stromal, and parenchymal cells, identifying promising LNP candidates. A novel small particle flow cytometry‐based protein adsorption analysis method is utilized to interrogate protein corona ...
