Although the complement of effectors is largely unchanged by disease-causing mutations, we were able to detect quantitative differences in the amount of specific effectors coimmunoprecipitated with wild-type and mutant Rab7 (Fig. 4B and C).

Although this complement of WNK8 target genes (which is based on altered transcript levels in the three mutants) is more stringently defined than the complement of the EDM2 target genes (which is only based on altered transcript levels in one mutant), the former is almost twice as large as the latter, suggesting that WNK8 may have a wider spectrum of biological roles than EDM2.
Although the complement system of amphioxus has been extensively studied, the expression in amphioxus and evolution of CFH gene remain unknown.
These findings suggest that although the full complement of the major RNA degradation mechanisms were present - and likely functional - early in eukaryotic evolution, the composition and function of the complexes is more variable than previously appreciated.
