RT hainanum (Ornithoctonus hainana) venom based on transcriptomic, peptidomic,
RT and genomic analyses.";
RL J. Proteome Res. 9:2550-2564(2010).
CC -!- FUNCTION: Probable ion channel inhibitor. {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Secreted {ECO:0000250}.
CC -!- TISSUE SPECIFICITY: Expressed by the venom gland.
CC -!- DOMAIN: The presence of a 'disulfide through disulfide knot'
CC structurally defines this protein as a knottin. {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the neurotoxin 14 (magi-1) family. 01 (HNTX-16)
CC subfamily. {ECO:0000305}.
CC -!- CAUTION: While it is structurally defined as a knottin it lacks the
CC conserved Cys residue in position 82. {ECO:0000305}.
