TREX-2-ORC Complex of D. melanogaster Participates in Nuclear Export of Histone mRNA
The TREX-2-ORC protein complex of D. melanogaster is necessary for the export of the bulk of synthesized poly(A)-containing mRNA molecules from the nucleus to the cytoplasm through the nuclear pores. However, the role of this complex in the export of other types of RNA remains unknown. We have shown that TREX-2-ORC participates in the nuclear export of histone mRNAs: it associates with histone mRNPs, binds to histone H3 mRNA at the 3'-terminal part of the coding region, and participates in the export of histone mRNAs from the nucleus to the cytoplasm.
期刊介绍：
Doklady Biochemistry and Biophysics is a journal consisting of English translations of articles published in Russian in biochemistry and biophysics sections of the Russian-language journal Doklady Akademii Nauk. The journal''s goal is to publish the most significant new research in biochemistry and biophysics carried out in Russia today or in collaboration with Russian authors. The journal accepts only articles in the Russian language that are submitted or recommended by acting Russian or foreign members of the Russian Academy of Sciences. The journal does not accept direct submissions in English.
