Interactions between mutants with defects in two Ca2(+)-dependent K+ currents of Paramecium tetraurelia.

The Journal of membrane biology - 1 Apr 1990

Preston R R, Saimi Y, Amberger E, Kung C

Abstract excerpt

Paramecium tetraurelia possesses two Ca2(+)-dependent K+ currents, activated upon depolarization IK(Ca,d), or upon hyperpolarization IK(Ca,h). The two currents are mediated by pharmacologically distinct ion channel populations. Three mutations of P. tetraurelia affect these currents. Pantophobiac A mutations (pntA) cause calmodulin sequence defects, resulting in the loss of both Ca2(+)-dependent K+ currents. A...
