Protein analysis without the pipeline
Structure prediction, mutation scoring, and scientific interpretation in one workflow. Built for researchers who need speed without sacrificing rigor.
Free analysis up to 5 sequences: no account required.
What foldfunc does
Three essential tools for protein research, integrated into one workflow.
Structure Prediction
Get accurate 3D structure models. View predicted confidence scores (pLDDT) and export to PDB format for downstream analysis.
Mutation Scoring
Score mutations across your entire sequence using language model embeddings. Identify conserved regions and predict effects on protein stability.
Scientific Context
Get AI-assisted interpretation rooted in structural biology. Understand functional implications and connect to relevant literature in seconds.
How it works
Paste your sequence
Input any protein sequence in single-letter format. Optionally add known mutation positions for targeted scoring.
Structure prediction runs
Your sequence is processed through deep learning tools to generate a 3D structure model.
Mutations are scored
Every position is evaluated for conservation and mutational tolerance.
AI synthesis
Receive scientific interpretation: family classification, key observations, and open research questions.
