Summary

OptoBAX is an optimized light-activated Cry2-BAX multi-component optogenetic system developed for one-click initiation of the BAX-mediated apoptotic cascade. It is used to trigger outer mitochondrial membrane permeabilization and induce early apoptotic events with light.

Usefulness & Problems

Why this is useful

OptoBAX provides optical control over initiation of apoptosis, enabling timed induction of BAX-dependent outer mitochondrial membrane permeabilization. In the cited work, it was used to measure the timing of morphological and biochemical changes during early apoptosis and to track MOMP-induced actin redistribution.

we have utilized OptoBAX in a series of experiments designed to measure the timing of the dramatic morphological and biochemical changes that occur in apoptotic cells following light-induced permeabilization of the outer mitochondrial membrane

Source:

in addition to reducing dark state cytotoxicity

Source:

The resulting optogenetic constructs have significantly reduced the frequency of light exposure required for the activation of membrane permeabilization

Source:

Previously, we have employed Cryptochrome 2 (Cry2)/CIB, a blue light photoreceptor protein - protein dimerization module from A. thaliana in conjunction with BAX, an OMM targeting pro-apoptotic protein, for light-mediated initiation of mitochondrial outer membrane permeabilization (MOMP) and downstream apoptosis.

Problem solved

This tool addresses the need for precise experimental initiation of the BAX-mediated apoptotic program so that early downstream cellular events can be temporally resolved. The optimized constructs also address dark-state cytotoxicity reported for earlier versions of the light-activated Cry2-BAX system.
