Drosophila insulin-like peptides (dILPs) regulate part of the signaling pathway that helps keep organs growing in proportion during development.
Present in every tissue of the body, ubiquitin appears to be involved in a dizzying array of functions, from cell cycle and division to organelle and ribosome biogenesis, as well as the response to viral infection. The protein plays at least two role
Despite its discovery as a protein that seems to show up everywhere, at least in eukaryotic cells, researchers are only beginning to scratch the surface of all of the cellular functions involving ubiquitin. As a monomer, ubiquitin can bind and tag ot
A rare peek inside the subterranean home of the naked mole-rat
Telomeres are repetitive, noncoding sequences that cap the ends of linear chromosomes. They consist of hexameric nucleotide sequences (TTAGGG in humans) repeated hundreds to thousands of times. Telomeres protect the protein-coding sequences of DNA on
A transition-state mimic has the power to bind an enzyme at its tipping point as strongly as any available inhibitor and more strongly than most, preventing enzymatic activity. In order to replicate the structure of an enzyme’s transition state, whic
Normal pancreatic function depends on the precise flow of calcium within and into the acinar cells of the organ. When food is eaten, low concentrations of the pancreas-stimulating hormone cholecystokinin or of the neurotransmitter acetylcholine cause
There are five steps of autophagosome biogenesis: induction, expansion, vesicle completion, fusion, and cargo degradation. While much has been learned over the past few decades about how this process works, the big question that remains is where the
The tongue may be the epicenter of taste sensation, but taste receptors are scattered throughout the digestive and respiratory tracts.
