Protein Domain·Research·Since 2021

Also known as: B-LID

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

Summary

The blue light-inducible degradation (B-LID) domain is a light-activated degron used to trigger loss of a fused protein in vivo. Available evidence indicates that it must be fused to the carboxy terminus of the target protein and can elicit light-dependent loss of Cactus function in developing Drosophila embryos.

Usefulness & Problems

Why this is useful

B-LID is useful for inducing protein loss with light, enabling temporal control of protein function in vivo. The supplied evidence specifically supports its use for light-dependent disruption of Cactus function during Drosophila embryogenesis.

Source:

We demonstrate that the photo-N-degron can be used to direct light-mediated degradation of proteins in Saccharomyces cerevisiae and Drosophila melanogaster with fine temporal control.

Source:

Here we describe the development and characterization of the photo-N-degron, a peptide tag that can be used in optogenetic studies of protein function in vivo.

Problem solved

B-LID helps solve the problem of controlling protein degradation with external light input rather than constitutive genetic perturbation. The evidence supports this as a way to achieve temporally controlled loss of target protein function in living systems.

Available evidence indicates that B-LID must be fused to the C terminus of the target protein. No additional implementation details such as cofactor requirements, expression system constraints, or illumination parameters are provided in the supplied evidence.

The supplied evidence provides only limited mechanistic and performance detail for B-LID, with no quantitative degradation kinetics, dynamic range, or wavelength specification. It also indicates a construct constraint, namely that the domain must be placed at the carboxy terminus of the targeted protein.

The B-LID domain is effective in eliciting light-dependent loss of Cactus function in developing Drosophila embryos.

the blue light-inducible degradation (B-LID) domain, a light-activated degron that must be placed at the carboxy terminus of targeted proteins, is also effective in eliciting light-dependent loss of Cactus function, as determined by embryonic dorsal-ventral patterning phenotypes.

The photo-N-degron functions as an N-terminal fusion and the B-LID domain functions as a C-terminal fusion to support light-dependent degradation in vivo.

importantly demonstrate that N- and C-terminal fusions to the photo-N-degron and the B-LID domain, respectively, support light-dependent degradation in vivo.

Comparisons

Source-backed strengths

The domain is explicitly described as a light-activated degron and was reported to be effective in eliciting light-dependent loss of Cactus function in developing Drosophila embryos. The same study also presents a broader context of light-mediated protein disruption in Saccharomyces cerevisiae and Drosophila melanogaster, although the organism-specific breadth for B-LID itself is limited in the supplied evidence.

We find that like the photo-N-degron, the blue light-inducible degradation (B-LID) domain ... is also effective in eliciting light-dependent loss of Cactus function, as determined by embryonic dorsal-ventral patterning phenotypes.

another previously described photosensitive degron (psd), which also must be located at the carboxy terminus of associated proteins, has little effect on Cactus-dependent phenotypes in response to illumination of developing embryos.

Compared with Jalpha helix

blue light-inducible degradation (B-LID) domain and Jalpha helix address a similar problem space because they share degradation.

Shared frame: same top-level item type; shared target processes: degradation; shared mechanisms: degradation; same primary input modality: light

blue light-inducible degradation (B-LID) domain and LOV2 domain-based optogenetic tool address a similar problem space because they share degradation.

Shared frame: same top-level item type; shared target processes: degradation; shared mechanisms: degradation; same primary input modality: light

Compared with photosensitive degron

blue light-inducible degradation (B-LID) domain and photosensitive degron address a similar problem space because they share degradation.

Shared frame: same top-level item type; shared target processes: degradation; shared mechanisms: degradation, light-induced protein degradation; same primary input modality: light

Relative tradeoffs: appears more independently replicated; looks easier to implement in practice.
