Figure 1. Abundance of transcripts expressed (FPKM, %) in the venom glands of Naja kaouthia from (a) Malaysia, NK-M; (b) Thailand, NK-T.

Toxins transcripts accounted for 41.2% (NK-M) and 82.0% (NK-T) of the total FPKM, respectively. Three-finger toxin (3FTx) is the most abundant toxin family expressed in the two venom glands (NK-M, 86.8%; NK-T, 97.0% of toxin FPKM). Abbreviations: 3FTx, three-finger toxin; L, long-chain; S, short-chain; NC, non-conventional; CRISP, cysteine-rich secretory protein; CVF, cobra venom factor; PLA₂, phospholipase A₂; SVMP, snake venom metalloproteinase; NGF, nerve growth factor; KSPI, Kunitz-type serine proteinase inhibitor; NP, natriuretic peptide; snaclec, C-type lectin/lectin-like protein; LAAO, l-amino acid oxidase; PDE, phosphodiesterase; AP, aminopeptidase; SVSP, snake venom serine protease; PLB, phospholipase-B; 5′NUC, 5′nucleotidase; DPP-IV, dipeptidylpeptidase-IV; CFs, coagulation factor; AChE, acetylcholinesterase and IGF, insulin-like growth factor.
