CC   -!- FUNCTION: Snake venom natriuretic peptide that exhibits hypotensive and
CC       vasodepressor activity. Acts by activating natriuretic receptors (NPR1
CC       and/or NPR2 and/or NPR3) (By similarity). {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Secreted {ECO:0000250}.
CC   -!- TISSUE SPECIFICITY: Expressed by the venom gland.
CC   -!- SIMILARITY: Belongs to the natriuretic peptide family. {ECO:0000305}.
