Ranscription PCR reactions were prepared using HotStarTaqH Master Mix Kit (Qiagen) with 2 ml of the synthesized cDNA in a 10 ml final volume. Q solution was included in the reaction (10 ) in NAMPT amplification in B. floridae and S. purpuratus. PNC and NAMPT were amplified with species-specific primers described in Table S6, with a final concentration of 0.2 mM. Thermocycling conditions were as follows: initial denaturation at 95uC for 15 min, 40 cycles at 95uC for 30 sec, variable annealing temperatures ranging from 52uC to 62uC (Table S6) for 1 min30 sec, and 72uC for 1 min, and a final extension step of 10 min at 72uC. All amplification products were visualized on 1.5 agarose gels and were confirmed by sequencing. For that, PCR products were purified with ExoSAP-IT (USB Corporation) by incubation at 37uC for 15 min, followed by enzyme inactivation for 15 min at 85uC. The resulting purified fragments were A-196 sequenced using an ABI Big Dye Terminator Cycle Sequencing Ready Reaction kit v 3.1 (Applied Biosystems) and analyzed in an ABI PRISM 3130xl (Applied Biosystems). Expressed Sequence Tag (EST) information was retrieved from available databases for B. floridae [64], S. purpuratus [65] and N. vectensis [66] and is detailed in Table S2.Figure SFigure S5 Invertebrate NAMPT synteny.

For each pair of species, mean divergence times are shown in million years as well as protein distances calculated from NAMPT and PNC amino acid alignments. 2100 was the value assigned for the cases where one of the proteins is absent from the species pair. (XLSX)Supporting InformationMovie S1 Evolutionary divergence between NAMPT andPNC homologues. Protein distances were plotted for each pair of species arranged accordingly to their respective divergence time. This plot shows that NAMPT is highly conserved across large evolutionary distances, while PNC is less conserved even in closely related species. Notice that in addition to being highly conserved, protein distances and evolutionary distances are correlated in NAMPT (quantified by the Kendall coefficient of 0.413).Ranscription PCR reactions were prepared using HotStarTaqH Master Mix Kit (Qiagen) with 2 ml of the synthesized cDNA in a 10 ml final volume.
