Design Notes
The part consists of humanized anti-CD3 and anti-GPA33 single-chain variable fragments (scFv) (BBa_K3117020, BBa_K3117021, BBa_K3117022, BBa_K3117023), which are connected by a flexible [GGGGS]4 linker (BBa_K3117004). The scFvs are formed by the variable regions of the heavy and light chain of the respective antibodies that are connected by either a [GGGGS]4 or [GGGGS]3 linker (BBa_K3117004, BBa_K3117028). The sequence contains a C-terminal His-Tag (BBa_K3117005) for easy purification and detection (Schmitt et al., 1993). Secretion of the protein is ensured by an Igk leader (BBa_K3117006). When the protein passes the membrane, this leader domain is cleaved off.
