Non-histone protein associated with centromeric heterochromatin in the mouse chromosome
Experimental Cell Research, 1977Abstract Distribution of protein in cytological preparations of the mouse metaphase chromosome was studied using protein-specific fluorochroming with dansyl chloride. Dansyl-fluorescence was relatively uniform along the axis of untreated chromosomes.

The partial amino acid sequence of a non-histone chromosomal protein
Biochemical and Biophysical Research Communications, 1976Abstract The amino acid sequence of the first thirty nine residues of the nonhistone chromosomal protein HMG-17 has been determined. Results presented here give a molecular weight of 11,000 for the protein. Some interesting sequence homology with the trout specific histone, histone-T, is noted.

Tissue specificity of tightly bound non-histone chromosomal proteins
Cell Differentiation, 1980Non-histone chromosomal proteins with high affinity for DNA were isolated from three different rat tissues (liver, spleen and kidney) and were analyzed by SDS-polyacrylamide gel electrophoresis. Each tissue showed a characteristic pattern of missing protein bands and in addition contained at least one unique band.

Continued synthesis of non-histone chromosomal proteins during mitosis
Biochemical and Biophysical Research Communications, 1970Abstract The synthesis of non-histone chromosomal proteins in synchronized HeLa S3 cells was studied in 3 phases of the cell cycle: S, G2 and mitosis. A 70–90% decrease in the rate of synthesis of total cellular protein and of chromatin-associated protein fractions extractable with low salt concentrations or with dilute acid was observed in cells in ...

Non-histone chromosomal proteins in normal and abnormal growth
Life Sciences, 1974Summary When quiescent populations of cells are stimulated to proliferate functional and structural changes occur in the chromatin of stimulated cells within the first hour after stimulation. Non-histone chromosomal proteins are responsible for the functional and structural changes occurring in chromatin of stimulated cells.

Chromosome replication and synthesis of non-histone proteins in giant polytene chromosomes
Chromosoma, 1968Synthesis of chromosomal proteins was studied by means of autoradiography in giant polytene chromosomes of Chironomus thummi. Incorporation of tryptophane-H3 into non-histone proteins of the chromosome does not increase during DNA synthesis. Grain count data reveal that chromosomes of cells which are actively replicating DNA do not differ from non ...

Purification of a low molecular weight non-histone chromosomal protein
Biochimica et Biophysica Acta (BBA) - Nucleic Acids and Protein Synthesis, 1980A non-histone chromosomal proteins was extracted from rat liver chromatin with 0.35 M NaCl and purified more than 2758 times to near homogeneity by hydroxyapatite, gel filtration, and phosphocellulose chromatography. The final fraction was greater than 95% pure as judged by non-denaturing gel electrophoresis.

Distribution and function of non-histone proteins in human chromosomes
Proceedings, annual meeting, Electron Microscopy Society of America, 1992The role of non-histone proteins in the structure and movements of mitotic chromosomes remains poorly understood. We describe here experiments aimed at characterization of the distribution of two very different classes of these proteins. The first is composed of integral components of the centromere (or primary constriction).

Developmental changes in non-histone chromosomal proteins of bullfrog (Rana catesbeiana)
Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 19821. Chromatins were isolated from liver, brain, kidney, spleen, heart muscle and erythrocytes of the bullfrog and its tadpole, Rana catesbeiana and their non-histone chromosomal proteins (NHC proteins) were compared by a simple electrophoretic method. 2.

Metabolically stable non-histone chromosomal proteins in growing maize roots
Cell Differentiation, 1978DNA and non-histone chromosomal proteins (NHCP) of meristematic cells of maize primary roots were double labelled in vivo with [3H]- or [14C] thymidine and [14C]- or [3H]-tryptophan respectively. The ratio of labelled tryptophan to labelled DNA was followed during the transition of the meristematic cells of the root tip into the distal zones of finally
