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.

Research finds associations between COVID-19 and persistent cognitive deficits

Much has been learned about SARS-CoV-2, the virus that causes the novel coronavirus, since the beginning of the COVID-19 pandemic. However, questions remain about the long-term impact of the virus on our bodies and brains.

Oxygen therapy may improve hypoxia-induced B cell abnormalities in COVID-19

Researchers in the United States have demonstrated early and persistent B cell abnormalities in patients with moderate or severe coronavirus disease 2019 (COVID-19) that may be largely driven by hypoxia.

Research shows how loss of de-N-glycosylation enzyme causes detrimental effects

Peptide: N-glycanase (NGLY1) is an evolutionarily conserved enzyme for removing N-linked glycans (N-glycans) from glycoproteins and is involved in proteostasis of N-glycoproteins in the cytosol. In 2012, a rare genetic disorder called NGLY1 deficiency was discovered by an exome analysis.

Study reviews natural drug candidates for potential treatment of COVID-19

A recent paper in the Saudi Journal of Biological Sciences seeks to open up new approaches by reviewing a list of compounds derived from plants and other natural sources, which have potential inhibitory activity against the coronavirus.

SARS-CoV-2 enzyme inhibitors among drugs screened for repurposing

A new bioRxiv* preprint describes the identification of some promising pharmaceutical compounds that could be developed as antiviral drugs against COVID-19.

Study explores therapeutic potential of exploiting autophagy cascade against COVID-19

Researchers recently reviewed current knowledge on links between autophagy and coronaviruses and how this knowledge can be used to repurpose autophagy modulators as potential treatment options for COVID-19. The review is published in the journal Frontiers in Microbiology.

Inflammatory brain injury higher in men with acute COVID-19, finds study

The COVID-19 pandemic has been associated with both short- and long-term neurologic complications, including stroke, brain fog and persistent tiredness. A new study concludes that the effects of SARS-CoV-2 on the central nervous system (CNS) are due to the endothelial injury and inflammation that this produces in the brain.

New enzyme may help curb chronic kidney disease

University of South Australia researchers have identified an enzyme that may help to curb chronic kidney disease, which affects approximately 700 million people worldwide.

Host cell transmembrane protein MARCH8 targets lysine residues to inhibit SARS-CoV-2 and other viruses

A new study deals with the inhibitory activity of a membrane protein that has broad-spectrum activity against multiple viruses, showing that this is due to its effect on cytoplasmic lysine residue incorporation into replicating virions.

Can an immunosuppressive cancer drug promote SARS-CoV-2 entry into host cells?

A new study shows that rapamycin, an immunosuppressive drug used in some cancers, and its analogs, may have an undesirable effect on viral entry into the host cells. This finding could inform their use to treat symptomatic COVID-19.

Researchers identify SARS-CoV-2 antiviral compounds using protein assay

During the process of SARS-CoV-2 infection, once the virus penetrates the host cell, two open reading frames, ORF1a and ORF1ab, are translated. ORF1ab is responsible for the production of 16 nonstructural proteins (nsp). Several viral proteases such as 3CLpro and PLpro (papain-like protease) produce 1-16 nsps. A new study has been published in bioRxiv* preprint server, which deals with identifying drugs that are effective as PLpro inhibitors.

Researchers describe a new approach to treating Parkinson's disease

Parkinson's disease is the second most common, age-related, neurodegenerative disease: In Germany alone, about 300,000 people are affected and experience sometimes major limitations to their quality of life.

New study maps SARS-CoV-2 and host protein interactions in detail

A new study has developed a systemic map detailing the mechanistic interactions and disruptions between severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and its host cell.

Researchers identify human BCAS3 and C16orf70 as novel autophagic proteins

Autophagy is an intracellular degradation process of cytosolic materials and damaged organelles. Researchers at Ubiquitin Project of TMIMS have been studying the molecular mechanism of mitophagy, the selective autophagy process to eliminate damaged mitochondria.

Study demonstrates intricate relationship between Prpf19 and Exoc7 in inherited ataxias

Spinocerebellar ataxia type 3 (SCA3), also known as Machado-Joseph Disease (MJD), describes the most common form of dominantly inherited ataxia in many populations worldwide, including Hong Kong and mainland China.

A missing protein explains the appearance of tumor cells in people 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.
