[Nuclear envelope of frog diplotene oocytes has telomere-binding activity]

A telomere-binding activity was found in the nuclear envelope of frog oocytes Rana temporaria by methods of binding on nitrocellulose filters and retardation. At present it is hardly possible to detect the proteins responsible for this activity. However, the results of this study allowed us to identify a specific mechanism of DNA-protein interaction, which provides the binding of the telomere to the envelope in meiotic cells.
