CC   -!- FUNCTION: Targets vasopressin-oxytocin related receptors.
CC       {ECO:0000250|UniProtKB:P05486}.
CC   -!- SUBCELLULAR LOCATION: Secreted {ECO:0000305|PubMed:32058072}.
CC   -!- TISSUE SPECIFICITY: Expressed by the venom gland.
CC       {ECO:0000305|PubMed:32058072}.
CC   -!- DOMAIN: The cysteine framework of the conopressin is C-C.
CC       {ECO:0000305}.
CC   -!- MISCELLANEOUS: The letter 'R' in the name 'Conopressin-R' proposed by
CC       Kumar and colleagues stands for the eighth residue, which differs
CC       between conopressins. {ECO:0000305|PubMed:32058072}.
CC   -!- SIMILARITY: Belongs to the vasopressin/oxytocin family. {ECO:0000305}.
