Rapid transfer of non-histone chromosomal proteins to the nucleus of living cells
Nature, 1978CHROMATIN of eukaryotic cells is composed of DNA, histones and non-histone chromosomal proteins. Histones are generally thought to be nonspecific gene repressers and components maintaining the structure of chromatin. On the other hand, recent reports suggest that non-histone chromosomal proteins activate regions of repressed DNA by their association ...

Studies on the degradation of high mobility group non-histone chromosomal proteins
Biochimica et Biophysica Acta (BBA) - Nucleic Acids and Protein Synthesis, 1978During the isolation of high mobility group non-histone proteins from calf thymus chromatin by methods described previously (e.g. Goodwin, G.H., Nicolas, R.H. and Johns, E.W. (1975) Biochim. Biophys, Acta. 405, 280--291) protein degradation occurs resulting in a number of proteins appearing in the chromatin extracts which are not present in high ...

Rapid turnover of non-histone chromosomal proteins in skeletal muscle
Experimental Cell Research, 1975Abstract Incorporation of 3 H-leucine into histones and non-histone chromosomal proteins was investigated in liver, a tissue in which proteins generally turn over rapidly, and in muscle, a tissue in which proteins turn over slowly. Incorporation into histones was low in both tissues.

Non-histone chromosomal proteins easily extractible from chick erythrocytes
Biochimica et Biophysica Acta (BBA) - Protein Structure, 1975Those non-histone chromosomal proteins which are easily extractible from chick erythrocytes differ substantially from proteins similarly extracted from other tissues of various species. Although a protein P1 was isolated along with histone H1 by extraction of calf thymus chromatin with HC1O4, the same procedure did not extract this protein from chick ...

On the relevance of non-histone proteins to the production of Giemsa banding patterns on chromosomes
Human Genetics, 1974Results are reported on the production of banding patterns stained with Giemasa. They are obtained from the application of different dyes and dye mixtures to metaphase chromosomes which were pretreated in various ways. The discussion of our findings in addition to those of other authors allows the following conclusions: 1.

Antibodies to Chromosomal Non-Histone Proteins in Malignant Cells
1983The exceptional selectivity of the immune response makes the use of antibodies to chromosomal proteins attractive for studies on the structure and function of chromatin. It is believed that alterations of cellular phenotype during differentiation and carcinogenesis are accompanied by changes in the composition of nuclear proteins, some of which may ...

Extraction and separation of core histones and non-histone chromosomal proteins
1998Abstract The participation of the nucleosome in DNA processing events such as transcriptional activation is now well established (see Editor’s Introduction). It has been shown. for example, that certain transcription factors can access their recognition sites within a nucleosome alone or with the help of the SWI/SNF complex.

Methods, 2006
Knowing the genomic distribution of chromosomal proteins and of histone modifications provides essential insight into function. The giant polytene chromosomes of the Drosophila larval salivary glands provide a high-resolution genomic map with a resolution exceeded only by chromatin immunoprecipitation.
