Figures:

Figure S1A: Multiple alignment of Orai protein homologues.

Figure S1B: Multiple alignment of Stim protein homologues.

Figure S1C: Multiple alignment of CDF protein homologues.

Figure S2A: Phylogenetic tree of Orai proteins. Protein abbreviations are as indicated in table S1. Clusters are labeled 1-6.

Figure S2B: Phylogenetic tree of Stim proteins. Protein abbreviations are as indicated in table S2. Clusters are labeled 1, 2 and 4-6, corresponding to the clusters in figure S2A.

Figure S2C: Phylogenetic tree of CDF proteins. Protein abbreviations are as indicated in table S3. Clusters are labeled 1-11.

Figure S3: Average hydropathy (dark line, top) and average similarity (light line, bottom) plots of Stim protein homologues (see table S2). This plot was generated with the AveHas program (Zhai and Saier, 2001) based on the multiple alignment shown in figure S1B.
