Figure S1. Alignment of amino acid sequences containing the C2, PDZ, and RhoGEF domains of five PsGEF proteins. The amino acid sequences containing the C2, PDZ, and RhoGEF domains of DmPsGEF (amino acid 272 to 1132), TcPsGEF (amino acid 601 to 1313), PhcPsGEF (amino acid 14 to 700), AmPsGEF (amino acid 595 to 1238), and LgPsGEF (amino acid 18 to 730) proteins are aligned by CLUSTALW program. The amino acid sequences of C2, PDZ, and RhoGEF domains are highlighted by red, green, and blue, respectively. Identical amino acids are indicated by asterisks, and the conserved amino acids are shown by either dots or colons. Only C2, PDZ, and RhoGEF domains show the significant similarity between five PsGEF proteins.
