BAD-BCL-2 complex
Definition
Target type: cellularcomponent
A heterodimeric protein complex consisting of BAD and BCL-2, members of the Bcl-2 family of anti- and proapoptotic regulators. [GOC:so, PMID:14634621]
The BAD-BCL-2 complex is a crucial component of the mitochondrial apoptotic pathway, a key mechanism for programmed cell death. This complex primarily resides in the **mitochondrial outer membrane** (MOM).
The BAD protein, a pro-apoptotic member of the BCL-2 family, interacts with BCL-2, an anti-apoptotic protein, at the MOM. The interaction between these two proteins occurs through specific BH3 domains (BCL-2 homology domain 3).
Here's a detailed breakdown of the cellular components involved:
* **Mitochondrial Outer Membrane (MOM):** This membrane is the primary site of the BAD-BCL-2 interaction. It acts as a platform for the complex formation, facilitating the regulation of apoptosis.
* **BAD Protein:** This pro-apoptotic protein has a BH3 domain that binds to the BH3-binding groove of BCL-2. BAD's role is to promote apoptosis by disrupting the anti-apoptotic function of BCL-2.
* **BCL-2 Protein:** This anti-apoptotic protein resides in the MOM and has a BH3-binding groove that can accommodate the BH3 domain of BAD. BCL-2 acts as a barrier against apoptosis by inhibiting the release of cytochrome c from the mitochondria.
The interaction between BAD and BCL-2 is crucial for regulating the delicate balance between life and death in cells. When BAD binds to BCL-2, it disrupts the protective function of BCL-2, allowing the release of cytochrome c, which triggers the caspase cascade and ultimately leads to apoptosis.'
