Hormone-induced diuretic-sensitive potassium transport in turkey erythrocytes is anion dependent

In turkey erythrocytes, the hormone-induced, diuretic-sensitive components of both unidirectional K+ influx and net salt uptake were Cl- dependent, with Br- partially able, and NO3(-) and SO42(-) unable to substitute as the main anion. Since the measured fluxes involve involve Na+/+ cotransport, these observations indicate that the unifying concept of an Na+/K+/2Cl- cotransport system (Geck, P., Pietrzyk, C., Burckhardt, B.-C., Pfeiffer, B. and Heinz, E. (1980) Biochim. Biophys. Acta 600, 432-447) may be extended to hormone-induced ion transport in avian erythrocytes.
