VEGFR-like

This year, the USTC iGEM team USTC_Parts has utilized the competitive binding of vascular endothelial growth factor (VEGF) to develop a targeted bacterial therapy for solid tumors. Our quest for the optimal VEGF-binding protein(or peptide) led us to an in-depth exploration of proteins structurally akin to the vascular endothelial growth factor receptor (VEGFR), which we have named VEGFR-like.

Figure 2. Plasmid Design

Here are all of our parts.Among them,BBa_K5302000-BBa_K5302007 are VEGFR-like and BBa_K5302008-BBa_K5302010 are masking peptides(VEGF-like).Others are plasmid. Please be advised that all listed genes have undergone codon optimization for our chassis strain, Escherichia coli Nissle 1917 (EcN). For those considering alternative chassis organisms, it is recommended to reassess the necessity of codon optimization.
