The acidocalcisome is an electron-dense acidic organelle which contains a matrix of pyrophosphate and polyphosphates with bound calcium and other cations. Its limiting membrane possesses a number of pumps and exchangers for the uptake and release of these elements. The acidocalcisome does not belong to the endocytic pathway and may represent a branch of the secretory pathway in trypanosomatids and apicomplexan parasites. The acidocalcisome is possibly involved in polyphosphate and cation storage and in adaptation of these microoganisms to environmental stress.
