Activated murine alpha-globin gene is not preferentially associated with the nuclear matrix
The International Journal of Biochemistry
|January 1, 1986
Abstract:
The association of the murine alpha-globin gene with the nuclear matrix was studied in three different states of the gene: inactive (EAT cells), potentially active (MEL cells) and active (induced MEL cells). When "native" nuclei were digested with DNase I it was found that the nuclear matrix was not enriched in alpha-globin DNA sequences in all three different types of cells. A nuclease-hypersensitive site in the 5'-flanking region of the alpha-globin gene was detected in the induced MEL-cells.
