家蚕bHLH转录因子BmASCa_4基因的生物信息学分析及功能预测

摘要

Silkworm （Bombyx mori） is a mode organism of Insecta, Lepidoptera. In October, 2003, Silk- worm genome sequencing project was finished, but there have been seldom reports on bioinformatics analysis and functional anticipation of bHLH transcription factor BmASCa4 gene in Bombyx mori. This article employed bioinformatic methods to study gene structure and function of bHLH transcription factor BmASCa4 in Bombyx mor/. These results are indicated, that gene structural information of bHLH transcription factor BmASCa4 is from only one EST sequence, which has no intron in coding district and that l＇sc gene encoded BmASCa4 and formation of neural precursors was promoted by BmA SCa4.%家蚕的基因测序工作已于2003年10月完成,但是对于其bHLH转录因子BmASCa4基因的生物信息学分析及功能预测鲜有报道。文章利用生物信息学的方法,就家蚕bHLH转录因子BmASCa4基因结构及功能进行了分析,研究结果表明：家蚕bHLH转录因子BmASCa4基因结构信息只来自一条EST序列,该基因在编码区内无内含子;BmASCa4由l＇sc基因编码,在促进神经前体的形成中发挥作用。
