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.

Scientists reveal how critical enzyme in the cell works

S-acylation is the process of chemically linking a lipid to protein via a thioester bond. It is an important process of the cell that regulates the localization and function of numerous proteins.

Absence of TRIM37 protein boosts genetic instability in patients with Mulibrey syndrome

Researchers from the Andalusian Centre for Molecular Biology and Regenerative Medicine (CABIMER), in collaboration with the Swiss Institute for Experimental Cancer Research (ISREC) have studied the mechanisms behind the higher tendency of people with Mulibrey syndrome to develop tumors.

Research clarifies regulatory impacts of ubiquitin-proteasome system on DNA damage repair

An international research team has clarified the regulatory mechanism of the ubiquitin-proteasome system (*1) in recognizing and repairing DNA that has been damaged by ultraviolet (UV) light.

Tau protein in Alzheimer's disease looks different at every dementia stage

Research into Alzheimer's disease has long focused on understanding the role of two key proteins, beta amyloid and the tau protein. Found in tangles in patients' brain tissue, a pathological form of the tau protein contributes to propagating the disease in the brain.

Study shows how UCH37 enzyme regulates a cell’s waste management system

Researchers reported the discovery of a new enzyme, called UCH37, that controls the waste management system of a cell.

A new look at an old technique for studying protein dynamics

A fresh new look at an old technique in protein biochemistry has shown that it should be reintroduced to the spectroscopy toolkit.

Enzyme SSH1 impairs disposal of damaged tau and mitochondria leaking toxins

In a healthy brain, the multistep waste clearance process known as autophagy routinely removes and degrades damaged cell components - including malformed proteins like tau and toxic mitochondria.

Study reveals new gene involved in motor neuron diseases

According to a study, failures in a quality control system that defends protein-building fidelity in cells can result in motor neuron degeneration.

Researchers develop scalable strategy to find novel molecular glue degraders

Despite immense efforts to improve pharmacology methods, over three-quarters of all human proteins still remain beyond the reach of therapeutic advancement.

Study shows how cells respond to nutrient deprivation

The idea of the cell as a city is a common introduction to biology, conjuring depictions of the cell's organelles as power plants, factories, roads, libraries, warehouses and more.

Study: PINK1 and Parkin work together to induce selective autophagy

Researchers at TMIMS have revealed that PINK1 (a serine/threonine kinase) and Parkin (a ubiquitin ligating enzyme: E3) work together to ubiquitylate the outer membrane proteins of damaged mitochondria to induce selective autophagy called mitophagy.

Research uncovers how 'reubiquitination' promotes elimination of misfolded membrane proteins

Chinese researchers recently discovered a protein quality control mechanism called "reubiquitination".

‘Terminator’ protein halts tumorigenesis

Essential processes in mammalian cells are controlled by proteins called transcription factors. For example, the transcription factor HIF-1 is triggered by a low-oxygen situation to cause the cell to adapt to decreased oxygen.

Study uncovers why developing nerve cells take a wrong turn

A group of scientists from CECAD, the Cluster of Excellence 'Cellular Stress Responses in Aging-Associated Diseases,' have found a mechanism by which neurodevelopmental diseases concerning neurons can be explained: The loss of a certain enzyme, UBE2K, impeded the differentiation of stem cells by silencing the expression of genes important for neuronal differentiation and, therefore, the development and generation of neurons.
