PLCzeta(ζ) initiates Ca2+ oscillations and egg activation at fertilization in mammals, but studies in mouse eggs fertilized by PLCζ knockout (KO) sperm imply that there is another slow acting factor causing Ca2+ release. Here, I propose a hypothesis for how this second sperm factor might cause Ca2+ oscillations in mouse eggs.
PLCzeta(ζ) 在哺乳动物受精时引发 Ca2+ 振荡和卵子激活,但用 PLCzeta 敲除 (KO) 精子受精的小鼠卵子的研究表明,还有另一种缓慢作用的因子导致 Ca2+ 释放。在这里,我提出了一个假设,即这种第二种精子因子如何在小鼠卵子中引发 Ca2+ 振荡。
