Popis:	A comparative study of nuclear distribution of the chromatin-remodeling protein ATRX in the oocytes of three species of insects in which the oocyte nucleus at the diplotene stage differs in structure, has been carried out using fluorescent and immunoelectron microscopy. In tohe oocyte nucleus of the tenebrionid beetles, Tribolium castaneum and Tenebrio molitor, ATRX preferably associates with the karyosphere (karyosome) that represents a result of concentration of the condensed chromosomes in a limited volume of the nucleus. In the oocyte nucleus of the house cricket, Acheta domesticus, in which a karyosphere does not form, the protein ATRX is distributed in the entire nuclear volume in association with the chromatin. The fact of ATRX presence in the extrachromosomal structures of the insect oocyte nucleus, the karyosphere capsule and specific nuclear bodies, is documented for the first time.
