The G4S linker is emerged as the most common linking peptides for scFvs. It is composed of the repeated sequence (Gly-Gly-Gly-Gly-Ser) and commonly found as either a 15-mer (G4S)3 or 20-mer(G4S)4 within scFv fragments. The G4S linker has become an integral part of the vast majority of CARs as it links the VH and VL recognition domains of scFvs. The G4S linker is commonly used in CARs targeting solid tumor antigens, such as HER2 and CEA, while the whitlow/218 linker peptide is predominantly used in CAR constructs targeting hematological malignancies such as CD19 CAR products.
