Bcl-2 family proteins

Bcl-2 family proteins are a group of molecules that regulate cell survival and death, primarily through controlling a process called apoptosis, or programmed cell death. Some members promote cell survival (anti-apoptotic), preventing unnecessary cell loss, while others encourage apoptosis, removing damaged or dangerous cells. The balance between these proteins ensures healthy development and prevents diseases like cancer. Understanding these proteins helps in developing treatments for conditions where cell death is abnormal.
