Ribosomes are essential for life, generating all of the proteins required for cells to grow. Mutations in some of the proteins that make ribosomes cause disorders characterized by bone marrow failure and anemia early in life, followed by elevated cancer risk in middle age. These disorders are generally called "ribosomopathies." How can ribosomopathies first appear as diseases caused by too few cells, but later turn into diseases caused by too many cells? This paradox has puzzled the...

Why do mutations in the proteins that make ribosomes cause bone marrow failure and anemia early in life, followed by elevated cancer risk in middle age? A new University of Maryland-led study suggests these disorders, called ribosomopathies, are caused by a sequence of mistakes at the molecular level. College Park, MD (PRWEB) March 31, 2014 Ribosomes are essential for life, generating all of the proteins required for cells to grow. Mutations in some of the proteins that make ribosomes...

Ribosomes, the cellular machines that build proteins, are themselves made up of dozens of proteins and a few looping strands of RNA. A new study, reported in the journal Nature, offers new clues about how the ribosome, the master assembler of proteins, also assembles itself. "The ribosome has more than 50 different parts – it has the complexity of a sewing machine in terms of the number of parts," said University of Illinois physics professor Taekjip Ha, who led the research with U. of...

Mitochondrial Ribosome Deciphered
2014-01-24 13:37:28

ETH Zurich Researchers at the Swiss Federal Institute of Technology (ETH) in Zurich have deciphered the structure of part of the ribosome found in mitochondria, the power plants of the cell. The scientists were able to benefit from advancements in the field of electron microscopy and capture images of the mitochondrial ribosome at a level of resolution never achieved before. The ribosome can be thought of as a decryption device housed within the cell. It is able to decipher the genetic...

Naked Mole Rat Longevity Perfect Proteins

redOrbit Staff & Wire Reports - Your Universe Online Researchers from the University of Rochester believe they have discovered the secret behind the longevity of the world’s longest-lived rodent: the creatures produce better protein than other members of their order. Naked mole rats, which typically live approximately 30 years and tend to remain healthy until their final days, possess a unique mechanism for building proteins, according to a recently-published study from research...

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. Scientists from the Florida campus of The Scripps Research Institute (TSRI) have uncovered how an enzyme co-factor can bestow specificity on a class of proteins with otherwise nonspecific biochemical activity. The protein in question helps in the assembly of ribosomes, large macromolecular machines that...

The findings have implications for the development of new anti-cancer drugs Scientists from the Florida campus of The Scripps Research Institute have identified a series of intricate biochemical steps that lead to the successful production of proteins, the basic working units of any cell. The study, which appears in the July 6, 2012 edition of the journal Cell, sheds light on the assembly of a structure called the ribosome, a large and complex protein-producing machine inside all living...

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. And 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. This finding challenges a long-held hypothesis about the early evolution of life. The study appears in the journal PLoS...
