Hypothesis
The study aims to determine the complete structure of mouse amelogenin under physiological conditions and understand its role in enamel formation.
Conclusion
The study concludes that amelogenin molecules form complex 3D structures that self-assemble through specific interactions at their N-termini.
Supporting Evidence
- Amelogenin self-assembles into supramolecular structures that influence enamel crystal size.
- NMR spectroscopy revealed four major structural motifs of amelogenin.
- Amelogenin's N-terminus is crucial for its self-assembly.
- The study identified a central region of amelogenin that remains monomeric even in assembled structures.
Takeaway
Amelogenin is a protein that helps form tooth enamel, and this study shows how it shapes itself into complex structures to do that.
Methodology
The study used NMR spectroscopy to analyze the structure of amelogenin and its fragments under physiological conditions.
Limitations
The study's findings may not fully represent amelogenin behavior in vivo due to the controlled experimental conditions.
