Patent attributes
The invention relates to an isolated or recombinant Na+/H+ exchanger comprising an isolated or recombinant Na+/H+ exchanger, particularly to the PBO-4 Na+/H+ exchanger. Also disclosed is an isolated or recombinant protein component of an H+-gated channel which can be affected by extracellular Ca2+ concentration. In particular, the invention relates to PBO-5 and/or PBO-8 and/or a H+-gated channel composed of PBO-5 and PBO-8. The invention relates to compounds isolated from a vertebrate organism, wherein said compounds comprise at least a part of a H+-gated channel or Na+/H+ exchanger. The invention also relates to a method for identifying a component of a H+-gated channel in a vertebrate organism.
