Figure 3From: Two Frequenins in Drosophila: unveiling the evolutionary history of an unusual Neuronal Calcium Sensor (NCS) duplicationPutative structure of the ancestral Frequenin. Predicted 3D structure of the ancestral Frequenin. The model is based on amino acid sequence reconstructed from the comparison of known Frequenins in insects (sequences in figure 2). Amino acid replacements found in D. melanogaster Frq1 and Frq2 are highlighted in blue and orange, respectively. Numbers indicate the position in the Frq1. C and N termini are indicated.Back to article page
