Patent number: 9006395Abstract: A single polypeptide is provided which comprises first and second domains. The first domain enables the polypeptide to cleave one or more vesicle or plasma-membrane associated proteins essential to exocytosis, and the second domain enables the polypeptide to be translocated into a target cell or increases the solubility of the polypeptide, or both. The polypeptide thus combines useful properties of a clostridial toxin, such as a botulinum or tetanus toxin, without the toxicity associated with the natural molecule. The polypeptide can also contain a third domain that targets it to a specific cell, rendering the polypeptide useful in inhibition of exocytosis in target cells. Fusion proteins comprising the polypeptide, nucleic acids encoding the polypeptide and methods of making the polypeptide are also provided. Controlled activation of the polypeptide, is possible and the polypeptide can be incorporated into vaccines and toxin assays.Type: GrantFiled: October 7, 2010Date of Patent: April 14, 2015Assignee: The Secretary of State for HealthInventors: Clifford Charles Shone, Keith Alan Foster, John Chaddock, Philip Marks, J.

Publication number: 20120141511Abstract: A novel agent for the targeted control of a mammalian cell activity can be used to control the interaction of particular cell types with their external environment. The agent has applications as a pharmaceutical for the treatment of a variety of disorders. An agent according to the invention comprises three Domains B, T and E, linked together in the following manner: Domain B-Domain T-Domain E where Domain B is the Binding Domain, which binds the agent to a Binding Site on the cell which undergoes endocytosis to produce an endosome; Domain T is the Translocation Domain, which translocates the agent from within the endosome across the endosomal membrane into the cytosol of the cell; and Domain E is the Effector Domain, which inhibits the ability of the Recyclable Membrane Vesicles to transport the Integral Membrane Proteins to the surface of the cell.Type: ApplicationFiled: October 11, 2011Publication date: June 7, 2012Inventors: Keith Alan Foster, Michael John Duggan, Clifford Charles Shone
