Author Contributions

DD initiated the Drosophila analyses that were done partly in collaboration with RAR, HEB, and PT. AR and JS were responsible for X. tropicalis analyses in collaboration with TS. AB and TS carried out PSI-Blast analyses. SK and AH contributed antibodies and unpublished data. CYB and SH provided C. elegans reagents and advised on the interpretation of the C. elegans data that were produced by PB under the supervision of SFN and TS. All other data were generated by VCS, SL, and NAM under the supervision of TS. The bulk of the paper was written by TS.
