Redundant mechanisms of calcium-induced calcium release underlying calcium waves during fertilization of sea urchin eggs.

Abstract
Propagating Ca2+ waves are a characteristic feature of Ca(2+)-linked signal transduction pathways. Intracellular Ca2+ waves are formed by regenerative stimulation of Ca2+ release from intracellular stores by Ca2+ itself. Mechanisms that rely on either inositol trisphosphate or ryanodine receptor channels have been proposed to account for Ca2+ waves in various cell types. Both channel types contributed to the Ca2+ wave during fertilization of sea urchin eggs. Alternative mechanisms of Ca2+ release imply redundancy but may also allow for modulation and diversity in the generation of Ca2+ waves.
