Interaction of Non-histone Chromosomal Proteins HMG1 and HMG2 with DNA [PDF]
Interaction between non-histone protein HMG1 or HMG2 and DNA has been studied by using thermal denaturation and circular dichroism (CD) spectroscopy. We have made the following observations. 1. The binding of each of these two proteins to DNA stabilizes the latter, as shown by an increase in melting temperature of 20 degrees C (from 45 degrees C to ...

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

Non‐histone Chromosomal Proteins [PDF]
We describe a method for fractionation of chromatin components by selective dissociation with salt in buffers containing 5 M urea in combination with chromatography on hydroxyapatite at 4 °C. This results in two histone and four non‐histone fractions which are recovered in high yield and with minimal proteolytic contamination.Template capacity ...

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

Effect of non-histone chromosomal proteins on transcription in vitro in sea-urchin [PDF]
Non-histone chromosomal proteins prepared from chromosomal material of the sea-urchin Paracentrotus lividus affect RNA synthesis in vitro. 1. The extent of transcription can be radically changed from inhibition to stimulation, depending on the DNA/non-histone chromosomal proteins ratio. 2. A correlation exists between stage of development and influence

SUMO control of centromere homeostasis
Centromeres are unique chromosomal loci that form the anchorage point for the mitotic spindle during mitosis and meiosis. Their position and function are specified by a unique chromatin domain featuring the histone H3 variant CENP-A.

Selfish chromosomal drive shapes recent centromeric histone evolution in monkeyflowers.
Centromeres are essential mediators of chromosomal segregation, but both centromeric DNA sequences and associated kinetochore proteins are paradoxically diverse across species.

The DNA intercalators ethidium bromide and propidium iodide also bind to core histones
Eukaryotic DNA is compacted in the form of chromatin, in a complex with histones and other non-histone proteins. The intimate association of DNA and histones in chromatin raises the possibility that DNA-interactive small molecules may bind to chromatin ...

Five RNA transcripts of about 1.2 to 1.7 kilobases were mapped to a part of the genome of insect iridescent virus type 6 (Chilo iridescent virus; CIV) between genome coordinates 0.832 and 0.856 within the EcoRI DNA fragment F.
