We have characterized a Drosophila gene that is a highly conserved homolog of the mammalian cyclic AMP (cAMP)-responsive transcription factors CREB and CREM. Uniquely among Drosophila genes characterized to date, it codes for a cAMP-responsive transcriptional activator. An alternatively spliced product of the same gene is a specific antagonist of cAMP-inducible transcription. Analysis of the splicing pattern of the gene suggests that the gene may be the predecessor of the mammalian CREB and CREM genes.
我们已经鉴定出一个果蝇基因,它是哺乳动物环磷酸腺苷(cAMP)反应性转录因子CREB和CREM的高度保守同源物。在迄今为止已鉴定的果蝇基因中,它独特地编码一种cAMP反应性转录激活因子。同一基因的一个选择性剪接产物是cAMP诱导转录的特异性拮抗剂。对该基因剪接模式的分析表明,该基因可能是哺乳动物CREB和CREM基因的前身。
