Excited to share our latest paper! We show that frog proteins bind and functionally neurotoxins involved in paralytic shellfish poisoning, with exciting potential applications in diagnostics and therapies!

Structural basis for saxitoxin congener binding and neutralization by anuran saxiphilins - Nature Communications
Dinoflagellates and cyanobacteria produce saxitoxin (STX) congeners that block voltage-gated sodium channels. Here authors show how amphibians may sequester STX congeners using a ‘lock and key’ mode, ...

I am working on a list of practical things that folks can do to help protect California amphibians, as part of a book project. Can you help me add to this list?
