WormMine: ExpressionPattern Expr9127

• Primary Identifier: Expr9127
• Subcellular Localization: Expressed in the cytoplasm with increasing levels in growing oocytes, peaking in the oocyte undergoing maturation. The level of OMA-1 protein remain very high following fertilization as well as throughout the first mitotic cycle. The antibody staining often included a slight punctate pattern of fluorescence. Immediately after the first mitotic division, the levels of OMA-1 protein rapidly decreased and became difficult to detect with antibody staining.
