How does Ubiquitin tagging fit into the process of protein degradation?
Answer . Ubiquitin tagging allows the 19S subunit of the 26S proteasome to recognize the potential protein substrate.
What is the role of ubiquitin?
Ubiquitin is a highly conserved regulatory protein found in eukaryotes. This protein starts a cascade effect to complete many different tasks, started by the E1 enzyme.
What would happen initially to cells that lack a functional ubiquitin?
Protein degradation would decrease due to ubiquitin's role in delivering to-be-broken-down proteins to the proteasomes.
Where is Ubiquitin found in the body?
Ubiquitin is found in almost all tissues within the body. It is a small regulatory protein which exists in all eukaryotic cells and was discovered in 1975.
