pMCherry+ET_Link_EGF_mEGFP

This plasmid contains the pMLB_mCherry plasmid backbone along with the heat-stable Enterotoxin ST-IA/ST-P, which is the non-virulent heat-stable enterotoxin produced by Enterotoxigenic E. coli. This signal peptide is linked to an EGF ligand bound to mEGFP via a GGSG linker. As a signal peptide, this protein contains a signal sequence that will interact with signal recognition particles to then direct ribosomes to the endoplasmic reticulum for co-translational insertion to take place.

Used primers BBa_K4686027 and BBa_K4686028 on the pMLB_mCherry plasmid backbone, and primers BBa_K4686034 and BBa_K4686030 on the T7_PB_SFFV_CD4_EGFf_mEGFP_TEVs_CD28_ plasmid. The BBa_K4686034 primer contained the signal peptide sequence sourced from UniProt, so the resulting insert contains the EGF ligand sequence from T7 as well as the signal peptide sequence. The pMLB_mCherry_GGBsMTS plasmid backbone was sourced from Piet de Boer. The T7 plasmid was sourced from our mentor Beatrice Ramm. The sequence for the Enterotoxin was sourced from UniProt.
