  • Title: [Interaction of various nuclear matrix proteins with DNA].
    Author: S'iakste NI.
    Journal: Biokhimiia; 1988 Feb; 53(2):256-62. PubMed ID: 3370251.
    Abstract:
    An attempt has been made to localize the previously detected strong and weak bonds of nuclear matrix proteins with DNA in some groups of proteins, using fractionation of the matrix into lamina and intranuclear fibrils, isolation of the "elementary globules", fractionation of matrix nucleoproteins on hydroxyapatite. It was shown that both weak and strong bonds are localized on the nuclear lamina and in the intranuclear fibrils. The single-stranded DNA enriched fraction of the matrix nucleoproteins contained mostly strong bonds. The strong bond is less resistant to pronase treatment. A method for isolating nuclear matrix nucleoprotein fractions carrying only strong or only weak bonds is proposed.
