Seminars in cell & developmental biology, 2006•ElsevierAt fertilization in mammals, the sperm activates development by causing a prolonged series
of intracellular Ca2+ oscillations that are generated by increased production of inositol
trisphosphate (InsP3). It appears that the sperm initiates InsP3 generation via the
introduction of a sperm factor into the egg after gamete membrane fusion. We recently
identified a sperm-specific form of phospholipase C (PLC), referred to as PLCζ (zeta). We

We review the evidence that PLCζ represents the sperm factor that activates development of the egg and discuss the characteristics of PLCζ that distinguish it from the somatic forms of PLC.
