(Symbiosis 2) Biomaterials Lab
Machine-translated · View original
A lab that harnesses the tendency of proteins to aggregate in order to detect arsenic.
AboutAbout the lab
Aggregation as a functional switch
The Biomaterials Lab investigates the benefits that protein aggregation brings to life.
Proteins function by adopting a three-dimensional structure, but when they can no longer maintain it, they may clump together and aggregate.
Aggregation looks like a "nuisance" state in which proteins lose their original function, but from another perspective it can serve as a functional switch for proteins.
Based on this idea, the lab studies proteins that respond to arsenic and microbial sensors.
Key terms
- Aggregation
- Proteins gathering together and solidifying.
- Functional switch
- A mechanism in which a protein's activity changes only when it receives a specific stimulus.
- Microbial sensor
- A mechanism that uses microorganisms themselves to signal, through a response, that a target substance is present.

ResearchResearch themes
The lab reexamines protein aggregation, in which proteins clump and solidify, from the viewpoint of its benefits to life. By using aggregation as a functional switch for proteins, it works toward building mechanisms that capture arsenic.
