Consomatins and signaling SSRP-like peptides are homologs with contrasting expression patterns. Comparative sequence alignments and gene structures of selected (A) consomatins and (B) signaling SSRP-like sequences retrieved from transcriptome and genome data. The position of the signal sequence (purple), propeptides (gray), mature toxin region (blue), mature signaling SSRP-like peptide region (green), and postpeptides (gray) are shown below alignments. Gene structures are shown using the same color codes. The phases of the introns are indicated above the introns, whereas the length is noted below. (C) Mean gene expression levels of consomatins and signaling SSRP-like sequences in the venom gland (n = 46), venom bulb (n = 2), salivary gland (n = 2), foot (n = 4), and circumoesophageal nerve ring (n = 4). Circles represent individual datapoints.
