BETA3 SUBUNIT COMPLEXED WITH AID

The structure was published by Chen, Y.-H., Li, M.-H., Zhang, Y., et al., Zhang, H., Tong, L., and Yang, J., in 2004 in a paper entitled "Structural Basis of the Alpha(1)-Beta Subunit Interaction of Voltage-Gated Ca(2+) Channels" (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.6 Å and deposited in 2004.

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