E-cadherin (Preproprotein, Mus Musculus)
This gene 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.
UCSF iGEM 2011 has created a BioBrick of only the extracellular domain of E-Cadherin (Mouse) BBa_K644000 but no BioBrick encoding the full E-cadherin protein has been submitted until now. BBa_K644000 also lacked detailed characterisation and the source was imprecise. Furthermore, we know now that E-cadherin requires interaction of its cytosolic domain for the production of stable cell-cell connections. (see Alberts 6th Ed. 2015, Ch. 19, p. 1040).
This gene was given to the UCL iGEM team 2017 by Prof. Stephen Price (UCL, not part of iGEM) after we searched for cadherin proteins suitable for our project. However, no sequence was known of the plasmid we were given and we sequenced the plasmid ourselves. Consecutive BLAST analysis showed a 99% similarity with Mus musculus cadherin 1 (Cdh1), mRNA (NCBI Reference Sequence: NM_009864.3, NCBI).
Three silent mutations were added into the sequence via side directed mutagenesis in order to remove one EcoRI and two PstI sites. Afterwards we sequence confirmed the entire gene.
