Elastin-like recombinamers (ELRs) are engineered protein polymers — recombinant, sequence-defined polypeptides — used in the source archive dental-enamel dossier as the basis of a "tuneable and resilient supramolecular matrix."
Role in the dossier
The Nature Communications abstract quoted in the dossier states that the authors "engineer a tuneable and resilient supramolecular matrix based on elastin-like recombinamers (ELRs) that imitates the structure and function of the enamel-developing matrix." The matrix is applied as a coating on teeth with different levels of erosion, where it is reported to be stable and to "trigger epitaxial growth of apatite nanocrystals."
The dossier gives no further detail on ELR composition, sequence design, molecular weight, crosslinking, or how "tuneable" and "resilient" are quantified. Those properties are asserted in the abstract, not demonstrated in the dossier.
Relationship to the patent family
The patent documents in the dossier describe different materials and should not be conflated with the ELR matrix:
- US2025145663A1 — Substrates Comprising Elastin-Like Polypeptides and Calcium Ions and US2024301032A1 — Substrates Comprising Elastin-Like Polypeptides and Calcium Ions claim "polypeptide substrates" embeddable with calcium ions and used to grow flower-shaped, onion-shaped and needle-like crystal structures. The dossier does not state whether these polypeptides are ELRs.
- CN109288685A — Amelogenin-Induced Fluoro-Calcium Silicate Biomimetic Mineralization and US2018236130A1 — Amelogenin-Chitosan Hydrogel for Dentin Hypersensitivity are amelogenin- and amelogenin/chitosan-based systems, not ELR systems.
