Similar but Not the Same, the Fission Yeast Processing Bodies
Cytoplasmic processing bodies (P-bodies) are RNA protein granules containing un translating mRNAs complexes with a set of translation repressors, the mRNA decapping machinery Dcp1-Dcp2 and the 5’-3’ exonuclease Xrn1 where mRNA decay can occur and have merged as important sub cellular structures that are involved in mRNA metabolism. Although components of P-bodies have been described in Schizosa...
متن کاملHow Fission Yeast Fission in the Middle
In fission yeast, we propose that the division plane may be positioned by the position of the premitotic nucleus, perhaps by a signal emanating from the nucleus. Gene products involved in the assembly of the ring and its temporal and spatial controls are beginning to be characterized. Some of these, such as mid1p, may be involved in signals that position the division site. In animal cells, the ...
متن کاملThe Spindle Pole Bodies Facilitate Nuclear Envelope Division during Closed Mitosis in Fission Yeast
Many organisms divide chromosomes within the confines of the nuclear envelope (NE) in a process known as closed mitosis. Thus, they must ensure coordination between segregation of the genetic material and division of the NE itself. Although many years of work have led to a reasonably clear understanding of mitotic spindle function in chromosome segregation, the NE division mechanism remains obs...
متن کاملDNA checkpoints in fission yeast.
The DNA integrity checkpoints ensure completion of DNA replication and DNA repair before entry into mitosis (O’Connell et al., 2000). Unreplicated DNA or unrepaired DNA will cause catastrophic chromosome segregation. The accompanying schematic shows the checkpoint proteins that monitor the state of DNA replication and DNA repair. Checkpoint proteins most probably interact with the replication c...
متن کاملCentromeric chromatin in fission yeast.
A fundamental requirement for life is the ability of cells to divide properly and to pass on to their daughters a full complement of genetic material. The centromere of the chromosome is essential for this process, as it provides the DNA sequences on which the kinetochore (the proteinaceous structure that links centromeric DNA to the spindle microtubules) assembles to allow segregation of the c...
