PutativeC. elegansFLP-GPCR-encoding gene homologues in 17 nematode parasites. Grey boxes indicate the presence of a flp-GPCR homologue, as identified via BLAST, in selected nematode species. Search queries employed and flp-GPCR predicted proteins identified are detailed in Supplementary Table 3 and Supplementary Figure 2, respectively. C. elegans flp-GPCRs not identified in the parasites included: npr-7, dmsr-9, dmsr-10, dmsr-11, dmsr-12, dmsr-13, dmsr-14, dmsr-15, dmsr-16, frpr-4, frpr-6, frpr-11, frpr-12 and frpr-16.
