Inhibition of trichocyst exocytosis and calcium influx in Paramecium by amiloride and divalent cations.

abstract：:cdc25 proteins are universally involved in the control of cell division. Using an original method of sequence analysis, cdc25 proteins from different sources were compared to protein phosphatases. Protein phosphatases could clearly be characterized as two distinct protein families, the phospho-seryl/threonyl phosphata...
