ISOLATION OF COMMON CARP b-ACTIN PROMOTER

ABSTRACT: Promoter in the transgene construct plays an important role on regulating of transgene expression level in transgenic fish. In fish transgenesis, researcher convinced  that  use  all-fish  promoter  more  safety and prospective.  This study was performed to isolate b-actin promoter, - the promoter which has ubiquitous, constitutive, house keeping  characteristics,  from common carp.  -actin promoter from common carp (ccBA) was isolated using PCR method with FBP1, RBP1 and RBP2 primers. Sequencing was performed using ABI PRISM 3100 machine and analysis of sequences was conducted using GENETYX version 7 software. The results of sequence analysis showed that the length of DNA fragment obtained approximately 1,5  kb  and  containing  the  evolutionary  conserved sequences of transcription factor for β-actin promoter including CCAT, CArG and TATA  box. The results demonstrated that isolated sequence was a common carp b-actin promoter.
Key words: Homologous promoter, GFP, carp transgenic
