Calcium ions are important in the regulation of mitotic apparatus assembly and in the control of chromosome movement. Changes in intracellular free calcium concentration, [Ca2+]i are achieved by an intracellular calcium-transport system which is highly conserved in different cell types. A membrane-bound protein of relative molecular mass (Mr) 46,000 (46K) is part of this transport system and has been implicated in the regulation of the [Ca2+]i changes associated with the course of mitosis. A monoclonal antibody against this 46K protein inhibits Ca2+-uptake into isolated Ca2+-sequestering membranes and specifically labels membranes associated with the mitotic apparatus of sea urchin embryos. Here we investigate the relationship between the intracellular calcium transport system and mitosis by injection of this monoclonal antibody into living mitotic sea urchin embryos. We find that after injection the intracellular free calcium increases up to 10(-6) M, the mitotic apparatus is rapidly destroyed and the cell is irreversibly blocked in its development.
