The structure was published by Faham, S., Yang, D., Bare, E., Yohannan, S., Whitelegge, J.P., and Bowie, J.U., in 2004 in a paper entitled "Side-chain Contributions to Membrane Protein Structure and Stability." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 1.8 Å and deposited in 2003.

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