Human and mouse TREK-1 potassium transport proteins are disclosed as well a method for using potassium transport proteins for identifying substances having anesthetic properties, such as producing a safe, reversible state of unconsciousness with concurrent amnesia and analgesia in a mammal upon inhalation, in a method comprising (a) contacting the test substance with a mammalian potassium transport protein, wherein said potassium transport protein exhibits outward-going potassium rectification; and (b) determining the potassium transport activity of the potassium transport protein, wherein an activation of potassium transport is indicative of the test substance having anesthetic properties.

Method for the identification of anesthetics

This invention relates to the cloning of a member of a new potassium channel named TWIK-1. More specifically, it relates to an isolated and purified nucleic acid molecule coding for a protein constituting a potassium channel exhibiting the proper-ties and structure of the TWIK-1 type channel, as well as the protein coded by this nucleic acid molecule. The invention also relates to the use of this nucleic acid molecule to transform cells, and the use of these cells expressing the potassium channels exhibiting the properties and structure of the TWIK-1 type channel for the screening of drugs.

Isolated TWIK-1 potassium channel proteins

This invention relates to a protein including a mammalian K+ channel with two pore domains, designated TREK2, that produces currents whose current-voltage relationship is weakly inward rectifying in high symmetrical K+ conditions. This invention further relates to the isolation and characterization of such protein, as well as a method using TREK2 to identify bioactive compounds having anesthetic properties.

Human TREK2, a stretch- and arachidonic acid-sensitive K+ channel activated by inhalational anesthetics and niluzole

The present invention relates to the cloning of a member of a new potassium channel named TWIK-1. More specifically, it relates to an isolated and purified nucleic acid molecule coding for a protein constituting a potassium channel exhibiting the properties and structure of the TWIK-1 type channel, as well as the protein coded by this nucleic acid molecule. The invention also relates to the use of this nucleic acid molecule to transform cells, and the use of these cells expressing the potassium channels exhibiting the properties and structure of the TWIK-1 type channel for the screening of drugs.
