Cone snail analogs of the pituitary hormones oxytocin/vasopressin and their carrier protein neurophysin. Proteomic and transcriptomic identification of conopressins and conophysins.
Biochimica et biophysica acta. Proteins and proteomics 20200210 5
Transcriptomic analysis of cone snail venom duct tissue has permitted the identification of diverse conopressin/conophysin precursor sequences from seven distinct Conus species. Multiple precursor isoforms are present in C.monile, C.lividus and C.loroisii. Aqueous extracts of the venom duct tissue from C.monile yield a band, at ~ 15-20 kDa on SDS-PAGE. In-gel trypsin digestion, followed by mass spectrometry establishes the presence of two distinct conopressin/conophysin isoforms that differ at p ...[more]
