ʙɪɴᴅᴄʀᴀꜰᴛ2 is out, and we're not waiting for the paper. The full code drops today, free for academic and industry use. We're releasing it early so you can start designing right now, and bring its full power to the current Adaptyv competition. github.com/PacesaLab/Bi...

First antidote to anthrax? 20 years ago we started working on S-acylation in the context of anthrax toxin entry. CMG2 is so hard to work on, but now we figured out! Amazing long term effort of Laurence Abrami, started by Sanja Blaskovic, with help of many lab members. www.nature.com/articles/s41...

New paper in Nature Communications: we identified ANTXR2 (CMG2) as the cellular receptor for C. perfringens NetF toxin, causing hemorrhagic enteritis in dogs and foals. ANTXR2 was previously known as the receptor for anthrax toxin PA. doi.org/10.1038/s414...

In collaboration with the Posthaus Lab, we identify ANTXR2—also the anthrax toxin receptor—as the receptor for Clostridium perfringens NetF pore forming toxin. Cryo-EM shows extensive contact between the pore and the receptor 🧬🧊🔬 #Microbiology #CryoEM #PoreFormingToxins doi.org/10.1101/2025...
