In this study, researchers cloned two L. merzbacheri β-actin promoter fragments of different length: SZ11 and SZ21 and analyzed their structural features. The mammalian expression vector pEGFP-N1 was used to construct eukaryotic expression vectors β1 pEGFP-N1-AFP III and β2 pEGFP-N1-AFP III in which fish type III antifreeze protein gene was used as the structural gene. The results showed that the cloned two fragments of β-actin promoters had the ability to drive the expression of the green fluorescent protein gene in BHK-21 cells. These data suggest that the vectors researchers constructed based on β-actin promoter could be exploited as all fish recombinant eukaryotic expression vector. ER -
