PTEN

特許 係属中 Phosphatase and tensin homolog (PTEN) is a protein that, in humans, is encoded by the PTEN gene.[2] Mutations of this gene are a step in the development of many cancers. PTEN acts as a tumor suppressor gene through the action of its phosphatase protein product. This phosphatase is involved in the regulation of the cell cycle, preventing cells from growing and dividing too rapidly.[3] It is one of the targets of an oncomiR, MIRN21.
