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.

Ubiquitin builds up an immune response

Ubiquitin is a small protein, which can be attached to other cellular proteins, a process known as ubiquitination.

New cell death pathway involved in sperm development

Heavy and bulky sperm would not be good swimmers. To trim down, sperm rely on cell death proteins called caspases, which facilitate the removal of unwanted cellular material and radically remodel these cells into their sleek, light shape.

New understanding of male fertility from enzyme discovery

Scientists have discovered a new enzyme involved in the degradation of proteins inside cells, a process that helps eliminate or recycle proteins that are no longer needed.

New findings on gene-transcription machinery

For some time, scientists have been tracking down the sequence of biochemical steps required to attract and assemble at the head end of a gene the molecular machinery needed to transcribe that gene to put to work the information it encodes.

Targeting key proteins of carcinogenesis

Misfolded and disused proteins are eliminated by a cellular shredder called the proteasome.

Scientists link cell's protein recycling systems

Many age-related neurological diseases are associated with defective proteins accumulating in nerve cells, suggesting that the cell's normal disposal mechanisms are not operating correctly.

25,000 genes that have clocks!

A chemical signal acts as time clock in the expression of genes controlled by a master gene called a coactivator, said Baylor College of Medicine researchers in a report that appears in the journal Cell today.

New candidate breast-cancer susceptibility gene

Researchers at the Abramson Family Cancer Research Institute of the University of Pennsylvania and the Dana-Farber Cancer Institute describe in this week's issue of Science a new candidate breast-cancer susceptibility gene.

New understanding of ubiquitylation

It turns out there's more than one way to skin a gene. New research from Rockefeller University suggests that two closely related DNA unpackaging mechanisms may not work the way scientists thought.

Disease associated prion protein oligomers inhibit the 26S proteasome

The rogue prion proteins responsible for diseases like BSE and vCJD can destroy brain cells by blocking the protein recycling process that helps keep cells healthy.

UNC-45 protein critical to proper formation of muscles

Proper formation of the proteins that power heart and skeletal muscle seems to rely on a precise concentration of a "chaperone" protein known as UNC-45, according to a new study.

How auxin regulates TIR1 in plants provides clues to new treatments for human diseases

For the first time, scientists from the University of Washington School of Medicine, Indiana University Bloomington and the University of Cambridge have determined how a plant hormone -- auxin -- interacts with its hormone receptor, called TIR1.

Recognition for cancer researchers

World-class cancer researchers whose science has significantly contributed to progress in the fight against cancer will be recognized April 14-18, 2007, by the American Association for Cancer Research (AACR) at its 2007 Annual Meeting in Los Angeles, Calif.

New drug target for herpes viruses

Scientists in the lab of Whitehead Institute Member Hidde Ploegh and the Harvard University lab of Rachelle Gaudet have solved the complex structure of a recently discovered protein that is found in a wide range of herpes viruses. This protein may prove to be a potential drug target.
