A comparison of nuclear and nucleolar matrix proteins from rat liver.
The comparison of the gel electrophoresis patterns of nuclear and nucleolar matrix proteins reveals marked differences between these structures. The nucleolar matrix contains 5 prominent protein bands ( mol.wt.: 8.2; 7.0; 5.6; 4.0 and 3.0 x 10 4 ) which are not found in nuclei. It is suggested that the nucleolar matrix has a distinct structure participating in selective interactions.
