Membrane protein mobility and exocytosis

Ca2+-ATPase activity in the gastric parietal cells of rat during perinatal development.

“…It is well known that mitochondria are the site of accumulation of calcium (30,32), and that A23187 induces the calcium release from the intracellular stores (38). Kurihara and Fujita (29)) have reported that calcium ions necessary for exocytosis and membrane fusion (8,12,18,37) are derived not only from the extracellular fluid but also from the mitochondrial matrix. Moreover several workers (28, 33-35, 47, 51-53) have noticed Ca2+-ATPase activity in the mitochondria of different types of secretory cells and they proposed that mitochondria are exclusively concerned with the Ca2+ accumulation and that Ca2+-ATPase activity in mitochondria may help to decrease intracellular Ca2-concentrations in cells.…”
