Expression Pattern :

Pattern  MEX-3 is present as a cytoplasmic protein. MEX-3 protein is first detected in oocytes shortly after cellularlization and the amount of protein appears to increase in oocytes as they mature. After fertilization, MEX-3 protein is evenly distributed throughout the cytoplasm of the 1 cell stage embryo. By the end of the 2-cell stage, MEX-3 protein appears more abundant in the AB blastomere than in P1 blastomere. In the 4-cell stage, the protein appears more abundant in the AB daughters than the P1 daughters. After 4-cell stage MEX-3 protein disappears from the embryo. In addition to general cytoplasmic staining, each of the MEX-3 antisera specifically stained distinct particles in P1 and in the P1 descendants P2, P3 and P4. Simultaneous staining with an anti-MEX-3 antibody and anti-P granule antibody, shows the particles stained by the MEX-3 antisera coincide with P granules in the blastomeres P1, P2, P3 and P4. However, the MEX-3 antisera do not stain P granules in the gonad or P granules in the germ cells of late stage embryos. Primary Identifier  Expr697
