Abstract: The present invention provides a method of identifying an agent which modulates an activity of a protein, wherein the protein is represented by the amino acid sequence of SEQ ID NO: 1 or has at least 90% amino acid sequence identity to SEQ ID NO: 1 and transports chloride ions across a cell membrane, comprising: (a) exposing cells which express the protein to the agent; and (b) measuring degree of chloride ion transport in the exposed cells, wherein a change in the degree of chloride ion transport compared to control cells, which express the protein but not exposed to the agent, is indicative of an agent capable of modulating an activity of the protein. The agents identified by this method can be used for the prevention or treatment of various diseases caused by the dysfunction of calcium activated chloride channel.

Abstract: The present invention relates to a method for producing a recombinant, spider toxin peptide and analgesic compositions containing said peptide. More specifically, the present invention relates to a method in which the gene for GsMTx4 is subcloned into a vector, so that it is linked to a secretion signal sequence of the alpha factor and under the control of methanol-inducible alcohol oxidase (AOX) promoter to construct a recombinant yeast expression plasmid. Yeast cells are transformed with this plasmid to produce the GsMTx4 peptide and analgesic compositions containing said peptide. The recombinant yeast expression system of the present invention affords a more stable method for producing GsMTx4 than its natural route. Thus the GsMTx4 peptide and its derivatives produced by the method of this invention can be used in the cure of related diseases such as heart failure as the peptide specifically inhibits mechanosensitive ion channels.

Abstract: Disclosed is the use of metabolites produced from arachiconic acid by the catalytic action of lipoxygenase as capsaicin-channel or- receptor agonists. The lipoxygenase metavolites of arachidonic acid and their derivatives can activate the capsaicin channel to excite pain nerves, causing serious pain. In contrast, the capsaicin channel activation of the pain nerves, so that an analgesic effects are brought about. The lipoxygenase metabolites of arachidonic acid can be used as an analgesic and in searching for and developing analgesics.
