Partial cDNA for human E-cadherin was provided by D. Rimm (Yale University, New Haven, CT) and subcloned into the pcDNA3 mammalian expression vector (Invitrogen), to generate Addgene plasmid 45772. Sequence analysis revealed that the 3′ end of the gene was missing after nucleotide 2644 (according to EMBL/GenBank/DDBJ under accession number L08599). This resulted in a truncation of the last 35 amino acids of the E-cadherin cytoplasmic domain and, as a result, did not contain the β-catenin binding region, as defined by Stappert and Kemler 1994. The COOH terminus of this truncation mutant (E-cadherin Δ β-catenin) ends at amino acid 844 (NH3-ASLSSD); the frameshift added a single histidine residue before a stop codon is introduced.
The full-length human E-cadherin was reengineered using RNA from human A431 cells and the RT-PCR method
(Primer A, 5′-TGACACCCGGGACAACGTTTATTA-3′, and Primer C, 5′-CTAGTCTAGACCCCTAGTGGTCCTCG-3′)
to generate a 425-bp fragment encoding the missing COOH-terminal residues. This fragment was sub-cloned into the truncated hEcad-Δ 35/pcDNA3 vector (Addgene plasmid 45772) to generate full-length hEcad/pcDNA3 (Addgene plasmid 45769).
These plasmids were created by your colleagues. Please acknowledge the Principal Investigator, cite the article in which the plasmids were described, and include Addgene in the Materials and Methods of your future publications.
