Classification of 69 SH2-containing protein sequences that represent various domain architectures. a: domain architecture as predicted by the Pfam HMMs; b: partitioning obtained by JACOP; c: Swiss-Prot IDs; d: the bitscore matrix with a colour code based on heat colours ranging from white for high values to red for low values, plus black for all bitscores that are below 27; e: the tree obtained by hierarchical clustering of the proteins based on Jaccard distances.
