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.

Intense exercise, fasting and hormones can enhance waste-protein removal, study shows

The body's ability to adapt to changing conditions and shifting physiologic demands is essential to survival. To do so, each cell must be able to dispose of damaged or unnecessary proteins--a quality-control mechanism critical for cellular performance and for the health of the entire organism.

MUSC researchers discover new mechanism for a class of anti-cancer drugs

Researchers at the Medical University of South Carolina reveal a novel binding site for a class of anti-cancer drugs known as E1 inhibitors. This finding could lead to the design of more efficient E1 inhibitors.

Researchers demonstrate strong evidence connecting bacterial pathogen and Alzheimer's pathogenesisis

New science uncovers how an unlikely culprit, Porphyromonas gingivalis (Pg) - the bacterium commonly associated with chronic gum disease - appears to drive Alzheimer's disease (AD) pathology.

The cytoskeleton of neurons found to play role in Alzheimer's disease

A researcher at the UPV/EHU has participated in a study describing what it is during the early stages of Alzheimer's that triggers the loss of dynamics and subsequent impairment of the dendritic spines, the compartments of the neurons responsible for receiving nerve impulses from other neurons.

Researchers identify a key regulator that stops excessive inflammation

A component has been identified by researchers in Umeå as a novel regulator of the immune system. It acts as a molecular switch to deactivate the innate immune system and has the ability to prevent certain diseases caused by an excessive activation of the immune system.

Study reveals how Parkinson's disease protein 'buys time' for cell repair

Australian researchers have discovered how a protein linked to Parkinson's disease may protect cells such as neurons in the brain.

Study uncovers new mechanism controlling the master cancer regulator

Of the more than 23,000 genes in the human genome, only a handful assume a very central role in signal transduction and growth regulation. Of these, the three genes encoding RAS proteins are particularly important, as they are found mutated in over 25% of human cancers.

Researchers identify LZTR1 as evolutionarily conserved component of RAS pathway

Mutations in RAS proteins initiate many of the most aggressive tumors, and the search for pharmacological inhibitors of these proteins has become a priority in the battle against cancer. Michail Steklov, Francesca Baietti, and colleagues from the Anna Sablina lab identified LZTR1 as an evolutionarily conserved component of the RAS pathway.

Inhibition of one protein clears toxic clumps seen in Parkinson's disease, study finds

A defining feature of Parkinson's disease is the clumps of alpha-synuclein protein that accumulate in the brain's motor control area, destroying dopamine-producing neurons.

One type of Chlamydia protein manipulates human cells in two different ways

When Chlamydia trachomatis, the bacterium that causes one of the most common sexually transmitted infections worldwide, infects a human cell, it hijacks parts of the host to build protective layers around itself.

New research to understand fundamental role of ubiquitin in cell death or survival

An effective regulation of programmed cell death is crucial for the correct development of embryos, a working innate immune system, and the prevention of cancer. How cells control the switch between cell survival and death, and which signaling pathways are involved, remain unclear.

Scientists discover new details about UHRF1 protein

Epigenetic changes often play an important role in cancer, because they cause the genetic material to be read incorrectly at certain locations. Genes that are especially critical are those that control the growth and death of cells.

UT Southwestern biochemist receives 2019 Breakthrough Prize in Life Sciences for innate immunity discovery

UT Southwestern biochemist Dr. Zhijian "James" Chen today was named winner of the prestigious 2019 Breakthrough Prize in Life Sciences for his discovery of the cGAS enzyme that launches the body's immune defense against infections and cancers.

Study shows how cellular waste disposal processes also promote inflammation

A study conducted at the University of California has revealed how cells use G-protein-coupled receptors (GPCRs) and their waste disposal systems to mediate inflammation.

Study gives new insights into how cells leverage GPCRs to control inflammation

G-protein-coupled receptors are everywhere in our bodies. They are embedded in our cell membranes, where they act as signal transducers, allowing cells to respond to their external environments.
