Complete dissociation of sister chromatid cohesion and subsequent induction of poleward movement of disjoined sisters are two essential events underlying chromosome segregation; however, how cells… (More)
We analyzed Polycomb group gene ph2alpha functionally in zebrafish embryos by a gene knock-down procedure using morpholino antisense oligos. Inhibition of ph2alpha message translation resulted in… (More)
The left-right (LR) axis is essential for the proper function of internal organs. In mammals and fish, left-sided Nodal expression governs LR patterning. Here, we show that the Polycomb group protein… (More)
Polycomb group (PcG) genes are required for stable inheritance of epigenetic states throughout development, a phenomenon termed cellular memory. In Drosophila and mice, the product of the E(z) gene,… (More)
Three histone H1 variants were identified in medaka fish and their sequence characteristics were analyzed. This paper reports one of these variants, termed H1-2, because of its possible implication… (More)
Separation of sister chromatids is a drastic and irreversible step in the cell cycle. The key biochemistry behind this event is the proteolysis mediated by the ubiquitin ligase called the anaphase… (More)
Polycomb group (PcG) genes are required for stable inheritance of epigenetic states across cell divisions, a phenomenon termed cellular memory. PcG proteins form multimeric nuclear complex which… (More)
