PSOPIA - Prediction Server of Protein-Protein Interactions

Home Page | Overview | Help page | Example results

Welcome to PSOPIA.

PSOPIA is an AODE for predicting protein-protein interactions using three seqeucne based features; (I) sequence similarities to a known interacting protein pair, (II) statistical propensities of domain pairs observed in interacting proteins and (III) a sum of edge weights along the shortest path between homologous proteins in a PPI network. Please see more details

This server is free and open to all users and there is no login requirement.

Please input a protein seqeunce pair(s) (see input format; maximum pairs = 10):
