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.

New Insights into How TRIM25 Fights RNA Viruses

Human bodies are attacked every single second of every day. The invading agents include bacteria, viruses, parasites, and toxins both living and non-living things that could impair how well bodies work.
