More Info: Ubiquitin specific protease 7 (USP7) supports cancer by positively affecting tumor growth and negatively affecting the patient’s immune response to tumors. USP7 inhibitors thus are an avenue of interest in potential cancer treatment. USP7 plays an important role in antagonizing p53 functions through multiple mechanisms. p53 is a critical tumor suppressor, and mutations in p53 are found in more than 50% of human cancers.
