Using a combination of biochemistry, molecular biology and live cell microscopy, we have discovered that PLCg is required for the initiation of the calcium increase during fertilization in starfish and sea urchin eggs. In collaboration with Dr. Kathy Foltz of the University of California at Santa Barbara and Dr. Laurinda Jaffe of the University of Connecticut Health Center, we have cloned a starfish PLCg cDNA from an arrayed oocyte cDNA library. We are currently using this clone as a tool to look for proteins that interact with PLCg in a fertilization-specific manner. We have determined that there are a suite of tyrosine-phosphorylated proteins, some from the sperm and some from the egg, that bind to PLCg only after fertilization. The identification of these proteins is a major goal of the laboratory in the coming years. Two graduate students from the laboratory (Leia Shuhaibar and Lu Zhong) have also developed a method for the visualization of changes in an enzyme called Mitogen-activated Protein Kinase (MAPK) using single cells. This allows us to gain a better understanding of the regulation of this enzyme during oocyte maturation and fertilization.
