Interactive exploration of the Drosophila protein-protein interaction network from FlyPredictome — 1.5 million AlphaFold-Multimer predictions scored with iLIS.
From 1.5 million pairwise predictions, 147,410 heterodimeric PPIs were classified as positive (iLIS ≥ 0.223). To construct this network, we selected positive PPIs supported by fly literature (FlyBase, BioGRID, MIST) or conserved interologs (DIOPT ≥ 4). After filtering for degree ≥ 2 and extracting the giant connected component:
5,224 proteins | 21,657 PPIs | 31 clusters
Leiden community detection identified 31 clusters, each corresponding to a coherent functional theme. Recursive sub-clustering resolved a three-level hierarchy from pathway-level modules down to individual protein complexes.
