1. Open the analyzer
Click Launch foldfunc from the homepage. Use Single mode for one protein or switch to Batch to analyze up to 20 sequences at once.
2. Input fields
Protein sequence
RequiredA protein sequence in single-letter amino acid format. Spaces, newlines, and carriage returns are stripped automatically. Only the 20 standard amino acids are accepted (A C D E F G H I K L M N P Q R S T V W Y). In Batch mode, paste multiple sequences in FASTA format — each entry begins with a >Name line followed by the sequence on the next line.
Minimum 10 residues. Maximum 2000 residues.
Protein name
OptionalA common name or identifier for the protein (e.g. "Lysozyme", "BRCA1"). Used to search for relevant literature and provides context to the AI interpretation. Leave blank if unknown.
Mutation positions
OptionalResidue positions you want targeted mutation scoring for, entered as a comma-separated list of integers. Positions are 1-indexed (the first residue is position 1). If left blank, foldfunc automatically selects positions across the full sequence.
