The invention provides a synthesis-inducible eucaryotic promoter having a transcriptional activity comprising, for example, a heavy metal-sensitive DNA sequence, derived from a natural promotor, of a base sequence of any one of SEQ ID NOS: 1 to 4; an inducer of the transcriptional activation activity thereof; a recombinant expression vector comprising a site for the insertion of an extraneous gene ligated to the above promotor; a eucaryotic expression kit comprising eucaryotic cells transfected with the above vector and the above inducer; and a method for expression of an extraneous gene in a eucaryotic system by using the same
本发明提供了一种具有转录活性的合成诱导型真核启动子,该启动子包括,例如,来源于天然启动子的重
金属敏感 DNA 序列,其碱基序列为
SEQ ID NOS:1至4;其转录活化活性的诱导剂;
重组表达载体,包括与上述启动子连接的插入外源
基因的位点;真核表达试剂盒,包括用上述载体和上述诱导剂转染的真核细胞;以及用上述试剂盒在真核系统中表达外源
基因的方法。
