Latest Ribosomal protein Stories
Ribosomes, the cellular machines that build proteins, are themselves made up of dozens of proteins and a few looping strands of RNA.
Researchers believe they have found the secret behind the longevity of the naked mole rat: the creatures' cells make nearly perfect proteins.
Synthetic biology researchers at Northwestern University, working with partners at Harvard Medical School, have for the first time synthesized ribosomes -- cell structures responsible for generating all proteins and enzymes in our bodies -- from scratch in a test tube.
Proteins, the workhorses of the body, can have more than one function, but they often need to be very specific in their action or they create cellular havoc, possibly leading to disease.
According to a new analysis, even before the ribosome's many working parts were recruited for protein synthesis, proteins also were on the scene and interacting with RNA.
In the beginning – of the ribosome, the cell's protein-building workbench – there were ribonucleic acids, the molecules we call RNA that today perform a host of vital functions in cells.
As part of a joint research effort with the University of Michigan, scientists from the Florida campus of The Scripps Research Institute have for the first time defined the structure of one of the cellâ€™s most basic engines, which is required for cell growth, as it assembles from its components.
A Howard Hughes Medical Institute investigator from Albany, New York, and an HHMI international research scholar from Buenos Aires, Argentina have combined their expertise to identify two peculiar features of the protein-making machinery of the parasite that causes Chagas disease. Their findings could help scientists develop a safe and effective drug for the disease, whose cardiac complications kill up to 30 percent of those infected.
- Stoppage; cessation (of labor).
- A standing still or idling (of mills, factories, etc.).
