The myc proteins are not associated with chromatin in mitotic cells.

Abstract

The protein products of cellular and viral myc oncogenes are detected in nuclei by immunofluorescence. No myc fluorescence is found in nucleoli. In mitotic cells the myc antigens are not found associated with metaphase chromosomes, but are diffusely distributed throughout the cytoplasm. Cytoplasmic myc fluorescence is first observed when chromatin begins to condense in early prophase. Granular nuclear myc fluorescence is again discerned in telophase cells, when the nuclear envelope is formed and becomes more prominent upon cytokinesis; concomitantly the diffuse cytoplasmic myc staining is lost. These results suggest that myc proteins not only bind to DNA or chromatin, but are also associated with other structural systems in the nuclei.
