Figure 1.

Protein and mRNA abundances were highly correlated between venom proteomes and venom gland transcriptomes. We compared RSEM estimates of transcripts per million (TPM) from venom gland transcriptomes to molar estimates of protein abundances in venoms for 11 individual snakes from 10 species and three families. All data were centered log-ratio (clr) transformed. Spearman’s rank correlations were high (ρ > 0.6) for 10 of 11 comparisons. Transcript abundances explained the majority of variation in protein abundance (i.e., R² > 0.5) for seven of the 11 comparisons.
