Immunoglobulin Folds are an important protein motif found immunology proteins such as antibodies. To learn more about antibodies and immunoglobulin folds, visit the RCSB Protein Databank's Molecule of the Month.

The immunoglobulin fold protein structure shown in the interactive window to the right is amino acids 121-220 of the Protein Databank file 1igt.pdb. When modeled with a 2 meter long Modeling Tie, the scale will be 2cm per amino acid.

Click and drag to rotate the protein structure. Hover your mouse over any atom to display what element it is and what amino acid it is part of.
