LOV-intein fusion protein

Multi-Component Switch·Research·Since 2016

Also known as: chimera, fusion protein

Taxonomy: Mechanism Branch / Architecture. Workflows sit above the mechanism and technique branches rather than replacing them.

Summary

The LOV-intein fusion protein is a light-responsive chimera in which DnaE split inteins flank the Avena sativa LOV2 photosensory domain. It enables blue-light upregulation of intein splicing to control post-translational formation of a functional protein, and this behavior was reported in bacterial and human cells.

Usefulness & Problems

Why this is useful

This tool provides optical control over protein formation at the post-translational level rather than through transcriptional regulation. The reported activity in both bacterial and human cells indicates utility for light-triggered activation of proteins across distinct cellular contexts.

Source:

The resulting chimera combines the activities of these two unrelated proteins to enable controlled formation of a functional protein via upregulation of intein splicing with blue light

Problem solved

It addresses the problem of controlling when a functional protein is assembled after expression has occurred. Specifically, it uses blue light to increase intein splicing, thereby gating formation of the active protein product.

Derived

The LOV-intein fusion protein is a light-responsive chimera composed of DnaE split inteins flanking the Avena sativa LOV2 domain. It enables blue-light upregulation of intein splicing, thereby controlling post-translational formation of a functional protein.

The reported construct consists of DnaE split inteins flanking the Avena sativa LOV2 domain. Activation is driven by blue light, and the literature reports use in bacterial and human cells, but the supplied evidence does not include construct architecture details beyond the fusion composition or any delivery/expression protocol specifics.

The supplied evidence does not provide quantitative performance metrics such as dynamic range, kinetics, background splicing, or reversibility. It also does not specify target proteins, illumination parameters, or the breadth of validation beyond the reported bacterial and human cell contexts.
