Design Notes

This year's project is a continuation of 2019's project. Last year our team (Korea_HS) designed CPP-scFv(P5) by engineering scFv(F8) that is inherently hyperstable. We have shown that CPP-scFv(P5) can enter the cell and recognize its cognate target protein, lysozyme in a reducing environment.

In 2020, we have designed hyperstable, cell-penetrating scFv targeting RAS protein (scFv(RAS)) based on the structure of RAS: anti-RAS antibody (PDB ID: 2vh5)
