Ubiquitin News and Research

RSS

Ubiquitin is a small regulatory protein that has been found in almost all cells (''ubiquitously'') with nuclei (eukaryotes). It directs proteins to recycling and other functions.

Lower glycemic index diet may delay onset of AMD-like lesions

Feeding older mice a lower glycemic index (GI) diet consisting of slowly-digested carbohydrates delays the onset of age-related, sight-threatening retinal lesions, according to a new study from the Laboratory for Nutrition and Vision Research at the Jean Mayer USDA Human Nutrition Research Center on Aging (USDA HNRCA) at Tufts University.

Scientists identify proteasome phosphatase that appears to regulate removal of damaged proteins

A study by scientists at the University of California, San Diego and UC Irvine has identified an enzyme called a proteasome phosphatase that appears to regulate removal of damaged proteins from a cell. The understanding of how this process works could have important implications for numerous diseases, including cancer and Parkinson's disease.

Individuals without ubiquitin ligase Nedd4L more likely to develop CF

Cystic fibrosis (CF), a chronic disease that clogs the lungs and leads to life-threatening lung infections, is caused by a genetic defect in a chloride channel called cystic fibrosis transmembrane conductase regulator.

Researchers discover mechanisms behind BRCA1 gene mutations in breast and ovarian cancer

It is widely known that mutations in the breast cancer susceptibility 1 (BRCA1) gene significantly increase the chance of developing breast and ovarian cancers, but the mechanisms at play are not fully understood. Now, researchers at Virginia Commonwealth University Massey Cancer Center have shown that certain BRCA1 mutations result in excessive, uncontrolled DNA repair, which challenges the prior assumption that mutations in BRCA1 only contribute to breast cancer through a reduction in function.

Chromatin might have another life as direct signaling molecule

Chromatin - the intertwined histone proteins and DNA that make up chromosomes - constantly receives messages that pour in from a cell's intricate signaling networks: Turn that gene on. Stifle that one. But chromatin also talks back, scientists at The University of Texas MD Anderson Cancer Center report today in the journal Cell, issuing orders affecting a protein that has nothing to do with chromatin's central role in gene transcription - the first step in protein formation.

Molecular mechanism of selected autophagy elucidated

Salmonella is widely prevalent in the animal kingdom. The reason we do not suffer from severe intestinal infections very often is due to our body's defence system, which manages to digest invading bacteria. This is why, generally speaking, a healthy human being will only fall ill if he consumes more than 100.000 salmonella bacteria via a contaminated food source, such as eggs or meat.
