Protein Pathfinder

Protein Interaction Pathfinder turns two gene names into a fully evidenced, visually explorable interaction pathway — combining STRING v12.5 network data, structural biology, and expression validation in one research tool. WHETHER YOU'RE MAPPING A SIGNALING CASCADE, checking whether two proteins can plausibly interact in a specific cell line, or just want to see a protein's real electrostatic surface, this app builds the evidence trail for you instead of leaving you to stitch together five different databases by hand. KEY FEATURES Pathway Discovery • Enter any two human gene symbols and find the shortest interaction path between them • Choose your evidence type: Functional, Physical, or directional Regulatory (v12.5 with activation/inhibition signs) • See the full STRING evidence breakdown for every edge — experimental, curated database, text mining, co-expression, neighborhood, gene…
