Application of the venom to small to medium diameter dorsal root ganglion cells for 10 s resulted in an inward current lasting several minutes when the venom was diluted in buffer at pH 6.1 but not at pH 7.4. Now we demonstrate that platypus venom has a potent action on putative nociceptors. We have previously shown that the venom contains a C-type natriuretic peptide that causes mast cell degranulation, and this probably contributes to the development of the painful response. However, platypus envenomation results in an immediate excruciating pain that develops into a very long-lasting hyperalgesia. Although envenomation of humans by many vertebrate and invertebrate species results in pain, this is often not the principal symptom of envenomation. The platypus (Ornithorhynchus anatinus), a uniquely Australian species, is one of the few living venomous mammals. The direct elevation of cGMP in vascular smoot. The genome sequence of the platypus, a protherian mammal, contained sequences homologous to 2 exons of an uncharacterized caspase gene present in the genome of chicken (supplementary fig. ovCNP-39 is equipotent with human/rat/porcine CNP-22 in eliciting cyclic guanosine 5'-monophosphate (cGMP) elevation in cultured vascular smooth muscle cells, suggesting that, like CNP, it acts through the ANPB natriuretic peptide receptor subtype. Identification of Caspase-17, a Novel Caspase Similar to Caspase-3, in the Platypus and Nonmammalian Vertebrates. These peptides produce hypotension in vivo and relax smooth muscle in vitro, but are poorly characterised in terms of physiological function. Elucidation of the 39-residue amino acid sequence confirms the homology with mammalian CNPs. In this study we describe the purification, detailed structure, synthesis and pharmacological characteristics of this peptide, which has been designated ovCNP-39 (Ornithorhynchus venom C-type natriuretic peptide). A peptide which relaxes rat uterine smooth muscle and exhibits homology with the mammalian C-type natriuretic peptide (CNP) has previously been identified in platypus (Ornithorhynchus anatinus) venom from its partial N-terminal amino acid sequence.
