Botulinum neurotoxins are comprised of multiple identifiable protein domains. Recent advances in understanding the relationships between domain structure and neurotoxin function have provided a number of opportunities to engineer innovative therapeutic proteins that utilise the neurotoxins and neurotoxin domains. For example, recent insights into the properties of the catalytic, translocation and binding domains open up opportunities to develop botulinum neurotoxins with enhanced properties of selectivity, potency and duration of action. In parallel, the broad scope for utilisation of the individual domains is becoming clearer as significant advancements are made to exploit the unique biology of the catalytic and translocation domains. These opportunities and the status of their development will be reviewed in this chapter. © Springer-Verlag Berlin Heidelberg 2013.


Patent
Allergan, Inc. and Syntaxin | Date: 2013-07-17

The present invention is directed to non-cytotoxic protein conjugates for inhibition or reduction of exocytic fusion in a nociceptive sensory afferent cell. The protein conjugates comprise: (i) a dynorphin Targeting Moiety (TM), wherein the TM is an agonist of a receptor present on a nociceptive sensory afferent cell, and wherein the receptor undergoes endocytosis to be incorporated into an endosome within the nociceptive sensory afferent cell; (ii) a non-cytotoxic protease or a fragment thereof, wherein the protease or protease fragment is capable of cleaving a protein of the exocytic fusion apparatus of the nociceptive sensory afferent cell; and (iii) a Translocation Domain, wherein the Translocation Domain translocates the protease or protease fragment from within the endosome, across the endosomal membrane, and into the cytosol of the nociceptive sensory afferent cell. Nucleic acid sequences encoding the protein conjugates, methods of preparing same and uses thereof are also described.

Patent
Syntaxin | Date: 2014-04-11

The present invention relates to a method for suppressing neuroendocrine disease. The therapy employs use of a non-cytotoxic protease, which is targeted to a neuroendocrine tumour cell, preferably via a somatostatin or cortistatin receptor, a GHRH receptor, a ghrelin receptor, a bombesin receptor, a urotensin receptor a melanin-concentrating hormone receptor 1; a KiSS-1 receptor or a prolactin-releasing peptide receptor. When so delivered, the protease is internalised and inhibits secretion from said tumour cell. The present invention also relates to polypeptides and nucleic acids for use in said methods.
