Phylogenetic trees for genes (A) C36B1.12 (Q93346), (B) F40F9.1a (Q8MQ56), F40F9.1b (Q8MQ55) and F40F9.2 (Q20241), (C) sft-4 (Q18864), and (D) ZK721.1 (Q9GYF0). The trees were constructed using PHYLOWIN with neighbor-joining method and PAM distances. 500 bootstrap replicates were run. All gene identifiers are Swiss-Prot accession numbers, except in (D) where XP_148505 is the NCBI accession number. The C. elegans genes studied here are marked with asterisks. F40F9.1 is predicted to have two splice variants; however, the putative proteins have the same length and only differ in the two most C-terminal amino acids. Species abbreviations: Arabidopsis thaliana (AT), Caenorhabditis elegans (CE), Drosophila melanogaster (DM), Fugu rubripes (FR), Homo sapiens (HS), Mus musculus (MM), Oryza sativa (OS), Rattus norvegicus (RN), Saccharomyces cerevisiae (SC), Schizosaccharomyces pombe (SP), Xenopus laevis (XL).
