RL   J. Am. Chem. Soc. 127:6207-6215(2005).
CC   -!- FUNCTION: May act as a neurotoxin.
CC   -!- SUBCELLULAR LOCATION: Secreted {ECO:0000269|PubMed:15853325}.
CC   -!- TISSUE SPECIFICITY: Expressed by the venom duct.
CC       {ECO:0000269|PubMed:15853325}.
CC   -!- PTM: Occurs in 2 forms which differ in the post-translational
CC       modification of Val-6. In the form conophan gld-V, Val-6 is D-valine.
CC       In the form gamma-hydroxyconophan gld-V*, Val-6 is D-4-hydroxyvaline.
CC       Both diastereomeric forms of D-hydroxyvaline may be produced.
CC       {ECO:0000269|PubMed:15853325}.
CC   -!- MASS SPECTROMETRY: Mass=847.3; Mass_error=0.1; Method=Electrospray;
CC       Note=Form conophan gld-V.; Evidence={ECO:0000269|PubMed:15853325};
CC   -!- MASS SPECTROMETRY: Mass=863.3; Mass_error=0.1; Method=Electrospray;
CC       Note=Form gamma-hydroxyconophan gld-V*.;
CC       Evidence={ECO:0000269|PubMed:15853325};
CC   -!- MISCELLANEOUS: The mature peptide does not contain cysteine residue.
CC       {ECO:0000305}.
CC   -!- SIMILARITY: Belongs to the conophan family. {ECO:0000305}.
