Nonhistone proteins control gene expression in reconstituted chromatin.
Chromatin was reconstituted from the purified DNA and histones of chicken erythrocytes and the nonhistone proteins of either chicken reticulocytes or chicken liver. Reconstituted chromatins, native chicken reticulocyte chromatin, and free DNA were transcribed with Escherichia coli RNA polymerase and the concentrations of globin-specific sequences in the RNA products were measured by hybridizati...
متن کاملPhenol-soluble nonhistone chromatin proteins in chronic lymphocytic leukemia.
The altered gene expression seen in cancer could relate to differences in nonhistone chromatin proteins between normal and malignant tumor cells. Phenol-soluble nonhistone chromatin proteins were isolated from human normal and leukemic (chronic lymphocytic leukemia) B-cells, as well as long-term cultured human B-lymphocyte cell lines. High-resolution two-dimensional electrophoretic maps identif...
متن کاملDNA unwinding component of the nonhistone chromatin proteins.
A subclass of nonhistone chromatin proteins from rat liver, previously shown to exhibit high affinity for DNA, has been fractionated by single-stranded DNA-agarose affinity chromatography. The protein fraction that bound to DNA-agarose in 0.19 M NaCl-buffer and was eluted with 2 M NaCl-buffer is enriched for a protein component of approximately 20,000 daltons and exhibits preferential binding t...

متن کاملTranscriptional transformation of Walker tumor chromatin by nonhistone proteins.
Nonhistone proteins fractionated from normal rat liver and Walker carcinosarcoma can stimulate chromatin-templated RNA synthesis in vitro. This has been demonstrated by using RNA polymerase prepared from rat liver. Walker tumor, or Micrococcus lutcus. The RNA isolated from these fractionated nonhistone proteins does not activate transcription from chromatin. As judged by DNA-RNA hybridization s...
