Objective To construct the expression vector of calcium- and integrin-binding protein (CIB)
and study its localization as a fusion protein in NIH3T3 cell. Methods Total RNA was extracted from human brain tissue for CIB sequence with RT-PCR
and then the obtained fragment was ligated into pCMV-myc vector. After confirmation with sequence analysis
the expression vector pCMV-myc-CIB was transformed into the NIH3T3 cell by Lipofectamin 2000. The protein expression was observed by immunofluorescent staining. Results DNA sequence analysis showed that the CIB cDNA had been successfully inserted into pCMV-myc expression vector. myc-CIB was expressed in the NIH3T3 cells transfected with pCMV-myc-CIB. Conclusion The eukaryotic expression vector containing CIB is successfully constructed and expressed in the cytoplasma of NIH3T3 cells.
