Description
Product Characteristics:
In plant cells, the vacuole functions as a major calcium store. Although a calmodulin-regulated Ca2+-ATPase (ACA4) is known to be present in prevacuolar compartments, the presence of an ACA-type Ca2+-ATPase in the mature vacuole of a plant cell has not been verified. Here we provide evidence that ACA11 localizes to the vacuole membrane. ACA11 tagged with GFP was expressed in stable transgenic plants, and visualized in root cells and protoplasts by confocal microscopy. A Ca2+-ATPase function for ACA11 was confirmed by complementation of yeast mutants.
Synonyms: calcium-transporting ATPase, Putative calcium-transporting ATPase 11, plasma membrane-type, Ca2+-ATPase isoform 11, autoinhibited Ca2+-ATPase 11Arabidopsis thaliana, ACA11_ARATH.
Target Information: This magnesium-dependent enzyme catalyzes the hydrolysis of ATP coupled with the translocation of calcium from the cytosol out of the cell or into organelles (By similarity)
