The Ubiquitin-Proteasome System Facilitates Membrane Fusion and Uncoating during Coronavirus Entry

39 views | Dec 19 2023

Inhibiting the ubiquitin-proteasome system (UPS) at the early infection stage severely impairs the infectivity of Infectious Bronchitis Virus (IBV) and Porcine Epidemic Diarrhea Virus (PEDV) by preventing membrane fusion, uncoating, initial translation, and replication events, highlighting the UPS as a potential target for antiviral therapies against coronaviruses.

109 views | Sep 02 2023

The study suggests that the Nedd8-activating enzyme (NAE), the neddylation process, and cullin RING ubiquitin ligases (CRLs) are potential targets for developing drugs against cytomegalovirus infections. [Read the Full Post]

Effects of arsenic on the topology and solubility of promyelocytic leukemia (PML)-nuclear bodies

50 views | Aug 21 2023

Trivalent arsenic (As3+) induces a solubility shift in PML, leading to rapid SUMOylation and late agglomeration of PML nuclear bodies (PML-NBs), which has implications for the regulation of intranuclear dynamics in the context of acute promyelocytic leukemia (APL). [Read the Full Post]
