PPI Prediction Challenge 1

We have a challenge for anyone who claims they can predict protein-protein interactions. 

Here is binding data: 15 novel binders, each bind one of 15 target proteins selectively (with some LC3B/GABARAP crosstalk, expected due to similarity). This is real data.

now next, lets see what alphafold3 predicts should bind within this 15x15 potential array of PPIs...

So, if you or someone you know thinks they can actually predict PPIs, prove it. Here is a link to our blinded sequence data:

Here are 18 engineered mini-protein binders:
