split-TurboID
Taxonomy: Mechanism Branch / Component. Workflows sit above the mechanism and technique branches rather than replacing them.
Summary
split-TurboID is a split proximity-labeling enzyme used in the Light Activated BioID (LAB) system, where its two halves are fused to the photodimeric proteins CRY2 and CIB1. Blue light induces CRY2–CIB1 association, reconstitutes split-TurboID, and triggers proximity-dependent biotinylation.
Usefulness & Problems
Why this is useful
In the LAB configuration, split-TurboID enables optically controlled proximity labeling with temporal gating by blue light. Source literature reports that LAB mapped E-cadherin-binding partners with higher accuracy and significantly fewer false positives than full TurboID.

Here, we present a light-activated proximity labeling technology for mapping protein-protein interactions at the cell membrane with high accuracy and precision.
Source:
We validate LAB in different cell types and demonstrate that it can identify known binding partners of proteins while reducing background labeling and false positives.
Source:
Here, we present a high spatial and temporal resolution technology that can be activated on demand using light, for high accuracy proximity labeling.
Problem solved
This tool helps address the problem of reducing background and false-positive labeling during proximity-dependent biotinylation experiments. By coupling split-enzyme reconstitution to light-induced CRY2–CIB1 dimerization, labeling is restricted to illuminated periods.

Need precise spatiotemporal control with light input
Derivedsplit-TurboID is used in the Light Activated BioID (LAB) system as two enzyme halves fused to the photodimeric proteins CRY2 and CIB1. Blue light induces CRY2–CIB1 association, reconstitutes split-TurboID, and initiates proximity-dependent biotinylation; removal of light dissociates the pair and halts labeling.

In LAB, the two halves of split-TurboID are genetically fused to CRY2 and CIB1, respectively. Activation requires blue light illumination to drive CRY2–CIB1 dimerization and reconstitute the labeling enzyme; the supplied evidence does not provide additional construct, expression, or cofactor details.
The supplied evidence is limited to the LAB implementation and does not establish performance across multiple targets, cell types, or organisms. Quantitative details such as labeling kinetics, biotin requirements, dynamic range, and residual dark-state activity are not provided in the supplied evidence.

Blue light exposure causes CRY2 and CIB1 to dimerize, reconstitute split-TurboID, and biotinylate proximate proteins in the LAB system.

Comparisons
Source-backed strengths
The reported strength of split-TurboID in LAB is light-dependent activation through CRY2–CIB1-mediated enzyme reconstitution. In the cited study, this implementation produced higher-accuracy mapping of E-cadherin-binding partners and significantly fewer false positives than TurboID.
Compared with light-oxygen-voltage sensing (LOV) domain
split-TurboID and light-oxygen-voltage sensing (LOV) domain address a similar problem space.
Shared frame: same top-level item type; shared mechanisms: heterodimerization; same primary input modality: light
Strengths here: appears more independently replicated; looks easier to implement in practice.
Compared with optogenetic RGS2
split-TurboID and optogenetic RGS2 address a similar problem space.
