Background Information and Alternate Names
Ubiquitin is a small regulatory protein that plays critical roles in various cellular processes in eukaryotic organisms. Its primary function is to tag proteins for degradation. This process, known as ubiquitylation, involves the attachment of ubiquitin molecules to substrate proteins, signaling them for destruction by the proteasome. Additionally, ubiquitylation also regulates many other cellular functions, including DNA repair, cell cycle regulation, and response to stress.
