WormMine: ExpressionPattern Expr573

• Pattern: mex-3 mRNA is detected in the syncytial core of gonad arm and distribute uniformly in oocyte and early 1-cell embryo. mex-3 mRNA is more abundant in AB and its daughter cells than P1 and its daughter cells. After 4-cell stage, mex-3 mRNA disappears. MEX-3 protein is present in oocytes and uniformly distributed until the first division, when they become more abundant in the anterior AB cell. At the 4-cell stage, AB daughters have more MEX-3. Both the mRNA and protein disappear after the 4-cell stage.
• Primary Identifier: Expr573
• Remark: early embryo(author) = 1-cell + 2-cell + 4-cell embryo(curator).
• Subcellular Localization: MEX-3 is cytoplasmic, and in the P cells, MEX-3 is associated with P granules.
