Roles of Tubulin Concentration during Prometaphase and Ran-GTP during Anaphase of Caenorhabditis elegans Meiosis

Life Science Alliance
Tubulin dimers concentrate within an ER spindle envelope because cytoplasmic organelles outside the envelope occupy significant volume. In many animal species, the oocyte meiotic spindle, which is required for chromosome segregation, forms without ...

Identifizierung und Charakterisierung eines neuen RanGTP-bindenden Proteins in der Hefe Saccharomyces cerevisiae

, 2002
Der kleinen GTPase Ran kommt in interphasischen Zellen eine zentrale Rolle beim Transport von Molekülen durch die Kernmembran zu.In höheren eukary- ontischen Zellen zerfällt während der Prometaphase der Mitose die Kern- membran.Es konnte neuerdings ...

Illustration of CFDP1 function in ensuring structural stability of centromeric heterochromatin and its effect on RCC1-mediated generation of RanGTP levels.

(A) CFDP1 binds to minor and major satellite heterochromatin and stabilizes a condensed chromatin architecture featuring normal H2A.Z chromatin levels and HP1α binding to H3K9me3 histone modifications. Chromatin bound RCC1 maintains high levels of RanGTP

Ran-GTP assembles a specialized spindle structure for accurate chromosome segregation in medaka early embryos

Nature Communications
Despite drastic cellular changes during cleavage, a mitotic spindle assembles in each blastomere to accurately segregate duplicated chromosomes. Mechanisms of mitotic spindle assembly have been extensively studied using small somatic cells.
