Figure 1

Biological clustering example. The figure shows a dendrogram describing the clustering of 37 proteins that matched the PROSITE "Serum Albumin Family" signature. The clustering advances from right to left along the axis that shows the similarity score at each point of the process. The vertical axis shows 16 initial clusters of proteins that the clustering starts with after the initial clustering stage. The initial clusters are numbered 1–16 and in parentheses show the number of proteins in them. Clusters 1–3 contain 5 Vitamin D Binding proteins (TPs). Clusters 4–13 contain 24 Albumin proteins (TPs). Cluster 14 contains 3 Afamin proteins (TPs). Clusters 15 and 16 contain the 5 FPs. The colors indicate the correct separation of this set into TPs and FPs.
