anti-Centromere Protein B (CENPB) Antibodies

Human Centromere Protein B (CENPB) interaction partners

1. Given that CENP-B is the only centromere protein that binds centromere-specific DNA elements, our study provides a new link between centromere DNA and unique epigenetic landscape of centromere chromatin

2. Upon cross-linking, the entire CENPA (show CENPA Antibodies)/CENPB/CENPC (show CENPC1 Antibodies)/CENPT (show CENPT Antibodies) complex is nuclease (show DCLRE1C Antibodies)-protected over an alpha-satellite dimer that comprises the fundamental unit of centromeric chromatin. We conclude that CENPA/CENPC (show CENPA Antibodies) and CENPT (show CENPT Antibodies) pathways for kinetochore assembly are physically integrated over young alpha-satellite dimers.

3. Findings indicate that expression of the scleroderma autoantigens IFI-16 (show IFI16 Antibodies) and CENPs (show APITD1 Antibodies), which are associated with severe vascular disease, is increased in vascular progenitors and mature endothelial cells. High level, lineage-enriched expression of autoantigens may explain the striking association between clinical phenotypes and the immune targeting of specific autoantigens.

4. The results indicated that CENPB boxes are highly conserved in Down syndrome (DS) patients and may not be responsible for Chr21 nondisjunction events. However, alphasatDNA in Chr21 is variable and deoxynucleotide deletions, mutations and polymorphisms may act as potential molecular diagnostic markers of DS.

5. CENP-B directly binds both CENP-A's amino-terminal tail and CENP-C (show CENPC1 Antibodies), a key nucleator of kinetochore assembly

6. The results revealed that CENP-B binding in the vicinity of the CENP-A (show CENPA Antibodies) nucleosome substantially stabilizes the CENP-A (show CENPA Antibodies) nucleosome on alphoid DNA in human cells.

7. Centromere protein B (CENP-B) as a novel interacting partner of HBZ (show HBZ Antibodies).

8. INMAP as a model regulator of CENP-B

9. N-terminal methylation is required for CENP-B's binding to the CENP-B box.

10. Human Nap1 (show IL8 Antibodies), an acidic histone chaperone, inhibited the non-specific binding of CENP-B to nucleosomes and apparently stimulated CENP-B binding to its cognate CENP-B box DNA.

Mouse (Murine) Centromere Protein B (CENPB) interaction partners

1. demonstrate a novel ADA3 (show TADA3 Antibodies) interaction with CENP-B-centromere that may account for its previously known function in mitosis

2. Cenpa (show CENPA Antibodies), Cenpb, and Bub3 (show BUB3 Antibodies), but not Cenpc (show CENPC1 Antibodies), interacted with PARP-1 (show PARP1 Antibodies)

3. This study shows that ICP0 induces the proteasomal-dependent degradation of the centromeric protein CENP-B in infected as well as ICP0-expressing cells.

4. Propose that CENP-B plays a dual role in centromere formation, ensuring de novo formation on DNA lacking a functional centromere but preventing the formation of excess centromeres on chromosomes.
