ReactomeInteractors Get Protein Interactors

Get protein-protein interaction partners for a specific protein from Reactome's IntAct-derived interaction data. Returns interactor accessions, gene names, confidence scores, and evidence counts. Interactions are curated from experimental data with molecular interaction (MI) scores. Example: get interactors for P04637 (TP53) returns 248 interactors including MDM2 (score 0.995, 119 evidences), EP300 (score 0.976), BRCA1 (score 0.944); for Q04206 (NF-kB p65/RELA) returns 105 interactors.
