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 โ€˜lock and keyโ€™ mode, ...

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!

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?
