Venom gland transcriptome and venom proteome abundance profiles for Spilotes sulphureus. Toxin contigs are expressed at high levels (a), with three-finger toxins exhibiting the highest levels of toxin gene expression (b). Toxin transcripts for venom proteins detected within the venom via LC-MS/MS are indicated with an asterisk (*). Abundances for transcripts belonging to each venom protein superfamily are shown (c) with superfamilies making up less than 1% combined to form the ‘other’ category. Relative abundances of each superfamily within the venom proteome are also shown (d). Abbreviations: 3FTx = three-finger toxin, CRiSP = cysteine-rich secretory protein, CTL = C-type lectin, KUN = Kunitz-type protease inhibitor, LAAO = l-amino acid oxidase, PLA₂_inhib = phospholipase A₂ inhibitor, PLB = phospholipase B, SVMP = snake venom metalloproteinase (PIII), SVMP_inhib = snake venom metalloproteinase inhibitor, NUC = 5′ nucleotidase, VEGF = venom endothelial growth factor, and VF = cobra venom factor.
