ST20 (Suppressor Of Tumorigenicity 20): ST20 ,also known as MINK1, is a protein belonging to the germinal center kinase (GCK) family. It participates in key cellular processes such as apoptosis, cytoskeletal reorganization, and cell migration, and is involved in signaling pathways that regulate cell survival and proliferation. Its role in tumor development and potential as a tumor suppressor remain active areas of research, with important implications for cancer biology and treatment.
