..., which makes their role in a given cell and/or organism complex to decipher. We have established the Paracentrotus lividus sea urchin embryo as a new model to study the role of PSEN. In the sea urchin embryo, the PSEN gene is present in unduplicated form and encodes a protein highly similar to human...

...Wen Ling Zhang; Philippe Huitorel; Anne-Marie Geneviere; Sandrine Chiri; Brigitte Ciapa Unfertilized sea urchin eggs that are arrested at G1 phase after completion of meiosis contain a highly phosphorylated mitogen-activated protein (MAP) kinase (MAPK), the ERK-like protein (ERK-LP). Several data...

... divisions. Furthermore, we observed that wortmannin, an inhibitor of PI 3-kinase that arrests the fertilized sea urchin eggs at the prometaphase stage, inhibited the inactivation of MAP kinase normally observed when the eggs divide, suggesting a role for PI 3-kinase in the deactivation process of MAP kinase...

... and screened a panel of monoclonal antibodies (mAb) generated against sea urchin sperm axonemal proteins. Antibodies were selected for their ability to block the motility of permeabilized sperm models. The antitubulin mAb B3 completely inhibited, at low concentrations, the flagellar motility of permeabilized...

... of centrioles it contains. In other experiments we show that centrosome reproduction is cytoplasmi- cally controlled; centrosomes repeatedly double in a normal fashion in physically enucleated sea urchin eggs and eggs in which DNA synthesis has been inhibited by aphidicolin. In addition, we show...
