Résumé
AIM: To clone and express the gene of SLC24A6, which provide the basis to illuminate the relationship between the SLC24A6 and insulin release. METHODS: The gene expression of SLC24A6 was analyzed in the insulinoma and normal pancreatic tissues by RT-PCR. The full-length cDNA sequence was subcloned into pET32a vector, and induced expression and purified in ROSSET (DE3) strain. At the same time, the ORF of SLC24A6 was cloned into green fluorescence protein vector pEGFP-C3 to study the location of SLC24A6 in the mouse insulinoma ?-TC3 cells. RESULTS: The mRNA expression of SLC24A6 in the human insulinoma tissue was significantly higher than that in normal pancreatic tissue. The fusion protein of SLC24A6 was a 80 kD protein and was purified successfully by prokaryotic vector in ROSSET strain. The localization of SLC24A6 in the mouse insulinoma ?-TC3 cells was located in the membrane of the cells. CONCLUSION: SLC24A6 might be related with insulin release. The prokaryotic expression of SLC24A6 provides the basis for the study on biological function and protein structure, and the location of SLC24A6 in the insulinoma cell will throw light on the relationship with insulin release.
