CDKN2B (Cyclin-Dependent Kinase Inhibitor 2B): CDKN2B functions as a critical regulator of cell cycle progression by inhibiting cyclin-dependent kinases. It plays a vital role in controlling the G1 phase of the cell cycle, preventing uncontrolled cell proliferation. Loss of CDKN2B function is frequently observed in various cancers, emphasizing its role as a tumor suppressor gene. Its regulation of cell cycle dynamics underscores its importance in cancer prevention and as a potential therapeutic target....
