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.

Findings reveals 'limpet-like' proteins can play a key role in DNA repair

UK scientists have found that a crafty family of 'limpet-like' proteins can play a crucial role in repairing DNA damage - according to two research papers published in Nature today (Wednesday). These findings could pave the way to the design of new anti-cancer drugs which target this process.

Researchers find how KEAP1 tumor suppressor works

A tumor-suppressing protein snatches up an important cancer-promoting enzyme and tags it with molecules that condemn it to destruction, a research team led by scientists at The University of Texas M. D. Anderson Cancer Center reports this week in the journal Molecular Cell.

Protein plays unexpected role protecting chromosome tips

A protein specialist that opens the genomic door for DNA repair and gene expression also turns out to be a multi-tasking workhorse that protects the tips of chromosomes and dabbles in a protein-destruction complex, a team lead by researchers at The University of Texas M. D. Anderson Cancer Center reports in the Aug. 13 edition of Molecular Cell.

Research looks at cellular stress response to low oxygen

Gary Chiang, Ph.D., and colleagues at Burnham Institute for Medical Research (Burnham) have elucidated how the stability of the REDD1 protein is regulated. The REDD1 protein is a critical inhibitor of the mTOR signaling pathway, which controls cell growth and proliferation.

Discovery of novel mechanism that could be targeted to prevent cancer spread

Researchers have discovered a key to the function of a specific protein that helps control the levels of other critical proteins within cells, including a protein that suppresses the spread of cancer. The new information about the mechanism of action of the protein, called gp78, may enable researchers to explore new types of therapies to prevent the spread of cancer. The study, by researchers at the National Cancer Institute (NCI), part of the National Institutes of Health, was published in the June 26, 2009, issue of Molecular Cell.
