WormMine: ExpressionPattern Expr1254

• Pattern: Staining of DNC-1 in one-cell and two-cell embryos revealed a striking accumulation at the cell-division remnant (also known as the residual body or midbody).
• Primary Identifier: Expr1254
• Remark: No detailed description on cellular expression pattern of later developmental stages.
• Subcellular Localization: Centrosomal and kinetochore staining was also seen. In addition, cytoplasmic staining was seen. Initially, the accumulation of DNC-1 at cell-division remnants appeared upon completion of the first meiosis during polar-body formation. This spot persisted until the end of the first mitosis. DNC-1 appeared at the leading edge of the cleavage furrow of one-cell stage embryos, and persisted at the cell-division remnant until the end of the two-cell stage.
