Figure 3.
Figure 3. D. rerio secretagogin and rat calbindin D[28K] have different quarternary domain arrangement. The domain II and III of D. rerio secretagogin (red) were superposed with the corresponding region of rat calbindin D[28K] (blue; PDB ID 2f33). In the resulting overlay, the domain I of secretagogin is rotated by almost 180° with respect to the core formed by domains II and III in both proteins. The green arrow points to the point from which structures diverge.
