The Torpedo marmorata Cl-channel

This channel has been sequenced by expression cloning by Jentsch and coworkers 

In preliminary experiments the laboratory of Jockusch and coworkers in collaboration with Al-Awqati [32] has used indanyloxyacetic acid (IAA-94, Fig. 2, cf. below) to purify proteins between 30 and 150 kDa, which appear to be responsible for CP-transport and seem to be absent in one form of hereditary myotonia [8]. During the process of editing this review the Jentsch group has succeeded to clone the skeletal muscle CP-channel and yet another CP-channel [125,127].
