1z92 Summary


structure of interleukin-2 with its alpha receptor

The structure was published by Rickert, M., Wang, X., Boulanger, M.J., Goriatcheva, N., and Garcia, K.C., in 2005 in a paper entitled "The structure of interleukin-2 complexed with its alpha receptor." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.8 Å and deposited in 2005.

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

This PDB entry contains a complex of 2 biomacromolecules, namely Interleukin-2 and Interleukin-2 receptor alpha chain.
