AF2BIND for Binding Site Prediction
AF2BIND is a logistic regression model on top of AlphaFold embeddings that predicts the probability that each residue in a protein is in a pocket. Binding site prediction is the problem of detecting where (which residues) on a protein are likely to interact with other molecules. This is also called a binding pocket, pocket, functional site, or sometimes a hotspot. Not all parts of a protein can be easily bound, so identifying where likely sites are can help scientists understand what the function of an unknown protein is, avoid disrupting important sites when engineering a protein, and decide whether or not a candidate protein is a good drug target.
How to Use AF2BIND
Predict pockets in P08100
resi | p(bind) |
---|---|
265 | 0.925 |
268 | 0.8773 |
212 | 0.8214 |
Inputs
- PDB File
- A single chain protein structure.
Outputs
- p(bind) Scores
For each residue in the input structure, a probability score of being in a pocket (0.0-1.0). Higher is better.
