This composite part is a device which efficiently encodes E-cadherin, a calcium-dependent cell adhesion molecule that functions in the establishment and maintenance of epithelial cell morphology during embryongenesis and adulthood. The encoded preproprotein undergoes proteolytic processing to generate a mature protein.



Figure 1: Construct Design. The CMV promoter was fused with the E-cadherin coding part by creating a 5'-UTR (untranslated region) which is essential for efficient translation. The resulting fusion construct contains a T7 promoter according to pcDNA3 standard, a standard mammalian expression plasmid. The CMV promoter and bGH terminator were chosen to ensure efficient gene expression.












Experimental approach

For testing this device we used CHO cells as our chassis of choice, which naturally lack E-cadherin expression but still maintain alpha- and beta-catenin expression. By chosing CHO cells as our chassis we, therefore, eliminated background noise.
