1g8i Summary



The structure was published by Bourne, Y., Dannenberg, J., Pollmann, V., Marchot, P., and Pongs, O., in 2001 in a paper entitled "Immunocytochemical localization and crystal structure of human frequenin (neuronal calcium sensor 1)." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 1.9 Å and deposited in 2000.

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