Ubiquitination assays

Ubiquitination assays are laboratory tests used to study a process called ubiquitination, where a small protein called ubiquitin attaches to other proteins in the cell. This tagging often signals the tagged proteins for degradation or helps regulate their function. By using specific techniques, scientists can detect and measure the level of ubiquitination on proteins. Understanding this process is crucial because it plays a key role in many cellular functions, including how cells respond to stress, regulate the cell cycle, and even in the development of diseases like cancer.
