Ligand-binding domain of Drosophila orphan nuclear receptor DHR38

The structure was published by Baker, K.D., Shewchuk, L.M., Korlova, T., et al., Thummel, C.S., Wilson, T.M., and Mangelsdorf, D.J., in 2003 in a paper entitled "The Drosophila orphan nuclear receptor DHR38 mediates an atypical ecdysteroid signaling pathway." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.3 Å and deposited in 2003.

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