Figure 2: Crystal structure of the beta-[3] core in complex with its alpha-[1] binding partner (AID). The [3] core can be divided into three regions: an SH3 domain (residues 60 -120 and 170 -175, gold), a HOOK region (residues 121 -169, purple) and a GK domain (residues 176 -360, green). Residues 226 -244 (forming the 4 helix) are disordered in this molecule but are well resolved in another one in the same asymmetric unit. Residues 422 -446 of Ca[V]1.2c containing the entire AID are coloured in orange. This and all subsequent ribbon diagrams were generated with the program RIBBONS28.
