The centromere is a specialized chromatin domain, present throughout the cell cycle, that acts as a platform on which the transient assembly of the kinetochore occurs during mitosis. De plus, nous expédions CENPT Anticorps (27) et CENPT Protéines (5) et beaucoup plus de produits pour cette protéine.

These results support the existence of 2 pathways for kinetochore assembly directed by CENP-C (Montrer CENPC1 Kits ELISA) and CENP-T/W, which can be reconstituted in Xenopus egg extracts.
report a novel disease gene encoding the constitutive inner kinetochore member CENPT, which is involved in kinetochore targeting and assembly, resulting in severe growth failure in two siblings of a consanguineous family
Upon cross-linking, the entire CENPA (Montrer CENPA Kits ELISA)/CENPB (Montrer CENPB Kits ELISA)/CENPC (Montrer CENPC1 Kits ELISA)/CENPT complex is nuclease-protected over an alpha-satellite dimer that comprises the fundamental unit of centromeric chromatin. We conclude that CENPA/CENPC (Montrer CENPA Kits ELISA) and CENPT pathways for kinetochore assembly are physically integrated over young alpha-satellite dimers.
Whereas CENP-C (Montrer CENPC1 Kits ELISA) recruits a single MIS12:NDC80 (Montrer NDC80 Kits ELISA) complex, the authors show here that CENP-T binds one MIS12:NDC80 (Montrer NDC80 Kits ELISA) and two NDC80 (Montrer NDC80 Kits ELISA) complexes upon phosphorylation by the mitotic CDK1 (Montrer CDK1 Kits ELISA):Cyclin B complex at three distinct CENP-T sites.
FACT chaperone stabilizes the soluble CENP-T/-W complex in the cell and promotes dynamics of exchange, enabling CENP-T/-W deposition at centromeres.
We used a synthetic system to dissect how CenH3(CENP-A (Montrer CENPA Kits ELISA)) contributes to the accumulation of CENP-C (Montrer CENPC1 Kits ELISA) and CENP-T, two key components that are necessary for the formation of functional kinetochores
CENP-T directly interacts with Ndc80, which in turn promotes KNL1/Mis12 complex recruitment at kinetochores during chromosome segregation.
CSN5 regulates the stability of the inner kinetochore components CENP-T and CENP-W, providing the first direct link between CSN5 and the mitotic apparatus, highlighting the role of CSN5 as a multifunctional cell cycle regulator.
CENP-T provides a structural platform for outer kinetochore assembly.
results reveal the molecular function of CENP-T proteins and demonstrate how the Ndc80 (Montrer NDC80 Kits ELISA) complex is anchored to centromeres in a manner that couples chromosome movement to spindle dynamics
The CENP-T/W complex assembles through a dynamic exchange mechanism in late S-phase and G2, is required for mitosis in each cell cycle and does not persist across cell generations.
The centromere is a specialized chromatin domain, present throughout the cell cycle, that acts as a platform on which the transient assembly of the kinetochore occurs during mitosis. All active centromeres are characterized by the presence of long arrays of nucleosomes in which CENPA (MIM 117139) replaces histone H3 (see MIM 601128). CENPT is an additional factor required for centromere assembly (Foltz et al., 2006
