Solution Structure of Human IL-13

The structure was published by Moy, F.J., Diblasio, E., Wilhelm, J., and Powers, R., in 2001 in a paper entitled "Solution structure of human IL-13 and implication for receptor binding." (abstract).

The structure was determined using NMR spectroscopy and deposited in 2001.

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

The PDB entry contains the structure of INTERLEUKIN-13. This molecule has the UniProt identifier P35225 (IL13_HUMAN)search. The sample contained 113 residues which is 92% of the natural sequence. Out of 113 residues 113 were observed and are deposited in the PDB.

The molecule is most likely monomeric.
