Tumor suppression genes are responsible for:

Tumor suppression genes play a crucial role in maintaining cellular integrity by regulating processes such as cell division and DNA repair. These genes produce proteins that help to control the cell cycle, ensuring that cells do not divide uncontrollably. They also play a pivotal role in monitoring and repairing DNA damage, thus preventing the accumulation of mutations that could lead to cancer. When tumor suppressor genes are functioning correctly, they enforce a safeguard that helps maintain normal growth patterns and cellular health.

While tumor suppressor genes can indeed trigger apoptosis, their primary functions encompass broader regulatory roles, including cell division control and ensuring the proper repair of DNA. In contrast, rapid cell division and unchecked cellular growth are indicative of mutations in these genes or their pathways, which can lead to oncogenesis if the regulatory functions fail. Thus, the critical function they serve in maintaining orderly cellular processes is encapsulated in their role in regulating cell division and DNA repair.
