Centromere and Pericentromere Transcription: Roles and Regulation … in Sickness and in Health

open access: yesFrontiers in Genetics, 2018
The chromosomal loci known as centromeres (CEN) mediate the equal distribution of the duplicated genome between both daughter cells. Specifically, centromeres recruit a protein complex named the kinetochore, that bi-orients the replicated chromosome ...

Conformational Studies of Two Non‐histone Chromosomal Proteins and Their Interactions with DNA [PDF]

open access: yesEuropean Journal of Biochemistry, 1976
The conformational properties of two non-histone chromosomal proteins (high-mobility-group proteins 1 and 2) have been studied by spectroscopic methods. The interaction of high-mobility-group protein 1 with DNA has also been studied. 1. Circular dichroism results indicate that in the presence of salt both proteins are 40-50% helical between pH 1 and 9.

Phosphorylation of non-histone proteins in the regulation of chromosome structure and function [PDF]

open access: yesJournal of Cellular Physiology, 1975
Non-histone chromosomal proteins are phosphorylated and dephosphorylated within the intact nucleus by two independent sets of reactions, a protein kinase reaction which transfers the terminal phosphate group of a variety of nucleoside and deoxynucleoside triphosphates to serine and threonine residues in the proteins, and a phosphatase reaction which ...

Skp, Cullin, F-box (SCF)-Met30 and SCF-Cdc4-Mediated Proteolysis of CENP-A Prevents Mislocalization of CENP-A for Chromosomal Stability in Budding Yeast.

open access: yesPLoS Genetics, 2020
Restricting the localization of the histone H3 variant CENP-A (Cse4 in yeast, CID in flies) to centromeres is essential for faithful chromosome segregation.

The Similarity between the Primary Structures of Two Non‐histone Chromosomal Proteins [PDF]

open access: yesEuropean Journal of Biochemistry, 1976
A comparison has been made of two non‐histone chromosomal proteins, high‐mobility‐group proteins 1 and 2. Peptides produced from the two proteins by various chemical and enzymic cleavages have been compared by polyacrylamide gel electrophoresis and peptide mapping.

Transcriptional and genomic mayhem due to aging-induced nucleosome loss in budding yeast

open access: yesMicrobial Cell, 2014
All eukaryotic genomes are assembled into a nucleoprotein structure termed chromatin, which is comprised of regular arrays of nucleosomes. Each nucleosome consists of eight core histone protein molecules around which the DNA is wrapped 1.75 times.

Karyotype rearrangements and telomere analysis in Myzus persicae (Hemiptera, Aphididae) strains collected on Lavandula sp. plants

open access: yesComparative Cytogenetics, 2014
Karyotype analysis of nine strains of the peach-potato aphid Myzus persicae (Sulzer, 1776), collected on Lavandula sp. plants, evidenced showed that five of them had a standard 2n = 12 karyotype, one possessed a fragmentation of the X chromosome ...

Post-translational modifications of epigenetic modifier TIP60: their role in cellular functions and cancer

open access: yesEpigenetics & Chromatin
TIP60 is a crucial lysine acetyltransferase protein that catalyzes the acetylation of histone and non-histone proteins. This enzyme plays a crucial role in maintaining genomic integrity, by participating in DNA damage repair, ensuring accurate ...

Rad51-Rad52 mediated maintenance of centromeric chromatin in Candida albicans.

open access: yesPLoS Genetics, 2014
Specification of the centromere location in most eukaryotes is not solely dependent on the DNA sequence. However, the non-genetic determinants of centromere identity are not clearly defined.

Cell cycle dependent methylation of Dam1 contributes to kinetochore integrity and faithful chromosome segregation.

open access: yesPLoS Genetics
The kinetochore, a megadalton structure composed of centromeric (CEN) DNA and protein complexes, is required for faithful chromosome segregation in eukaryotes.
