Ubiquitin Ligases

Ubiquitin ligases, also known as E3 enzymes, are essential proteins in the human body that play an important role in the regulation of cellular processes. They facilitate the attachment, or “tagging”, of ubiquitin molecules to other cellular proteins, marking them for destruction or other modifications. These modifications are important for ensuring normal, healthy cell function. Ubiquitin ligases are also being studied for possible use in treating diseases such as cancer and Alzheimer’s, as well as for their role in antibiotic resistance. Understanding how these proteins work and how they can be manipulated could open up new therapeutic treatments or drug targets in the future.
