Part:BBa_K2549001

suface-expressed CD19

Surface-expressed CD19 (surCD19) is built by joining CD8α signal peptide, CD19 extracellular domain and the transmembrane region of PDGFRβ (from N terminal to C terminal). Additional HA tag on its N terminal and a Myc tag on its C terminal to facilitate detection by antibodies^[1]. CD8α peptide guides synthesized fusion protein to pass the translocon^[2] into the endoplasmic reticulum^[3], and the fusion protein will be later sugar modified in Golgi^[4], presented on the plasma membrane and located to the outside of the cell. Transmembrane region of PDGFRβ embeds surCD19 on the membrane. It was used as the antigen for Part:BBa_K2549005.
