Regulation of tubulin gene expression during embryogenesis in drosophila melanogaster

摘要: Abstract Four different tubulins have been identified that are expressed during embryogenesis in Drosophila melanogaster. Two α-tubulin subunits ( α 1 and 2 ) one β-tubulin subunit β throughout embryonic development. A second 3 is only for a short period mid-embyronic Synthesis of -tubulin vitro rabbit reticulocyte translation system directed by RNA extracted from embryos at the stage when protein expressed. Thus we conclude mRNA encoding transcribed brief synthesis. The expression accompanied coordinate transient increase level synthesis α-tubulins, thereby maintaining an approximately equimolar α- embryogenesis.
