Ubiquitin

Ubiquitin. By Mr. Szerminski Sample 4U CCT. General info: - it is a regulatory protein that has been found in almost all tissues of eukaryotes - one of its functions: it directs protein recycling - can attach to proteins and label them for destruction.

Ubiquitin

Ubiquitination is a key regulatory mechanism attaching the small protein modifier ubiquitin to protein substrates, thereby modifying their structure, cellular location, function, or targeting them for destruction via proteolysis. The process of protein ubiquitylation regulates many aspects of cell function and provides a wealth of drug target opportunities to many therapeutic areas including cancers, cardiovascular, metabolism, inflammation, diabetes, neurodegeneration and infectious diseases. https://www.creative-biogene.com/Services/Drug-Discovery-Services/Ubiquitin-Screening-Profiling-Services.html

Ubiquitin and Ubiquitin-like Modifiers

In addition to ubiquitin, there is a small family of ubiquitin-like modifiers. The SUMOs and ISG15 are the other two ULMs that have been implicated as modifiers involved in HPV viral processes. There are four human SUMO genes encoding SUMOs 1-4. Small ubiquitinrelated modifier (Sumo-1) shares only 18% sequence identity with ubiquitin, whereas Nedd8 (neural precursor cell expressed developmentally downregulated-8) shares an 80% sequence homology with ubiquitin.
