What the tool is doing

ERDDBs are BRET-based live-cell biosensors that detect estrogen receptor homo- and heterodimerization and are used for rapid identification of estrogenic endocrine-disrupting chemicals.

Source 1DOI PubMed

Resources required

The abstract supports a BRET biosensor design with optimized donor and acceptor placement, HaloTag as the acceptor, a P2A linker in the highest-sensitivity prototype, and stable cell lines for screening.

Source 1DOI PubMed

What problem it solves

The tool is presented as a solution to the lack of a comprehensive live-cell screening approach for compounds affecting all ER dimer forms.

Source 1DOI PubMed

What it does not solve

The abstract does not show that the platform fully classifies every screened estrogen analog, since only 26 of 72 were successfully classified.

Source 1DOI PubMed

Alternatives

The abstract contrasts ERDDBs with the prior lack of a comprehensive live-cell approach, but does not name a specific alternative assay in the paper abstract.

Evidence Snippets

Here, we developed ER dimerization-detecting biosensors (ERDDBs), based on bioluminescence resonance energy transfer, for dimerization detection and rapid eEDC identification.

Before this study, a comprehensive live-cell screening approach for estrogenic endocrine-disrupting chemicals affecting all ER dimer forms was lacking.

Claim 2optimization resultsupports2024Source 1DOI PubMed

Using HaloTag as the acceptor and a P2A peptide linker produced the highest-sensitivity ERDDB prototype among those tested.
