  1. For each query protein, the corresponding Mnemiopsis protein model is listed with the E-value of the top BLAST result. The Mnemiopsis protein model was then used as a query in a reciprocal best BLAST search of the non-redundant protein database (NCBI) and the top result is listed along with the E-value of the BLAST result. RNA-seq data supports the developmental mRNA gene expression of each of these protein models. BLAST: Basic Local Alignment Search Tool; ML: Mnemiopsis leidyi; PDE: phosphodiesterase; TRP: transient receptor potential.
