1alu Summary



The structure was published by Somers, W., Stahl, M., and Seehra, J.S., in 1997 in a paper entitled "1.9 A crystal structure of interleukin 6: implications for a novel mode of receptor dimerization and signaling." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 1.9 Å and deposited in 1997.

The experimental data on which the structure is based was not deposited.

The PDB entry contains the structure of INTERLEUKIN-6. This molecule has the UniProt identifier P05231 (IL6_HUMAN)search. The sample contained 186 residues which is < 90% of the natural sequence. Out of 186 residues 154 were observed and are deposited in the PDB.

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 has more than one probable quaternary state observed. For more details see the quaternary structure page.
