Crystal structure of Fel d 1- the major cat allergen

The structure was published by Kaiser, L., Gronlund, H., Sandalova, T., et al., van Hage-Hamsten, M., Achour, A., and Schneider, G., in 2003 in a paper entitled "The crystal structure of the major cat allergen Fel d 1, a member of the secretoglobin family." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 1.85 Å and deposited in 2003.

The experimental data on which the structure is based was also deposited.

This PDB entry contains multiple copies of the structure of Major allergen I polypeptide, fused chain 2, chain 1.

It also contains one or more heterogenic compounds (e.g., ligands, co-factors, ions, modified amino acids, etc.); see here for a complete list.

The molecule most likely forms homodimers.
