Regulatory role of the N-terminus of the vacuolar calcium-ATPase in Cauliflower
The vacuolar calmodulin (CaM)-stimulated Ca(2+)-ATPase, BCA1p, in cauliflower (Brassica oleracea) has an extended N terminus, which was suggested to contain a CaM-binding domain (S. Malmström, P. Askerlund, M.G. Palmgren [1997] FEBS Lett 400: 324-328). The goal of the present study was to determine the role of the N terminus in regulating BCA1p. Western analysis using three different antisera show
