Predict Protein–Protein Interaction

Choose a mode below — a single pair, two groups, or all pairs within one file.

1 Pairwise Protein–Protein Interaction One pair

Protein sequences only (amino-acid letters). Each sequence must be 20–1500 residues.

2 PPI Among Different Groups Two files · all-vs-all

FASTA files only (.fasta, .fa, .txt), max 2 MB each, up to 20 sequences per file, each 20–1500 residues. Total pairs (group1 × group2) must not exceed 400.

3 PPI Among a Single Group One file · internal pairs

FASTA file only (.fasta, .fa, .txt), max 2 MB, up to 20 sequences, each 20–1500 residues. Total pairs — n × (n − 1) / 2 — must not exceed 400.
