Calsequestrin is a high capacity low affinity Ca2+-binding protein thought to be essential for the function of the intracellular rapid releasable Ca2+ pool of a variety of animal cells. Here we show that two types of plant tissues, cultured Streptanthus tortuosus cells and spinach leaves, contain a form of calsequestrin. In subcellular fractions of S. tortuosus cells, Stains-all staining reveals a metachromatically blue-staining 56,000-Da protein enriched in the microsomal fraction. This… CONTINUE READING
