Physiological and pharmacological modulation of BAX

Area of Science:

• Molecular Biology
• Cell Death Mechanisms
• Drug Discovery

Background:

• Bcl-2-associated X protein (BAX) is a key mediator of mitochondrial outer membrane permeabilization (MOMP) during regulated cell death.
• Dysregulation of BAX contributes to various human diseases, making it a significant therapeutic target.
• Targeting BAX has been challenging due to difficulties in understanding its activation mechanisms and identifying druggable sites.

Purpose of the Study:

• To review recent structure-function insights into BAX activation.
• To highlight identified regulatory surfaces controlling BAX.
• To emphasize novel therapeutic strategies targeting BAX.

Main Methods:

• Review of recent scientific literature on BAX.
• Analysis of structure-function relationships of BAX.
• Discussion of small molecule modulators of BAX.

Main Results:

• Recent studies have elucidated critical structure-function relationships of BAX.
• Specific regulatory surfaces controlling BAX activation have been identified.
• Development of small molecule modulators (orthosteric, allosteric, oligomerization) offers new therapeutic avenues.

Conclusions:

• Understanding BAX activation mechanisms is crucial for therapeutic development.
• Novel small molecule modulators provide opportunities for biological investigation and drug development targeting BAX.
• Targeting BAX represents a promising strategy for treating diseases associated with aberrant cell death.
