InaK-linker-Im7_Cell membrane anchoring protein and immune protein complex
Inak is a kind of ice nucleoprotein of Pseudomonas syringae KCTC1832. Ice nucleoprotein is a kind of protein that can promote the formation of ice crystals in organisms. Its N-terminal domain can be tightly anchored to the surface of E. coli cells as an anchor moda, so as to enable surface display. linker here is a short peptide sequence used to link Inak and Im7. Im7 is an immune protein that has a high affinity with CL7, an engineered variant of colicin CE7, and incubation allows Inak-linker-Im7 to bind to CL7-Linker-SFGFP (another composite part we registered), thus anchoring the entire system to the membrane surface. Finally, the Inak-linker-Im7-CL7-linker-sfGFP system is displayed on the surface of the membrane, where sfGFP is a green fluorescent protein, which can verify the success of anchoring, and then it can be replaced with single-chain antibodies, nano-antibodies, etc., to play a targeting role. It should be noted that the system we designed uses the high affinity of CL7 and Im7, so some components can be flexibly replaced according to needs, and are suitable for different use scenarios according to different needs. For example, according to different cells to replace the ice nucleated protein, according to different targeting targets to replace sfGFP with different single-chain antibodies, nano antibodies and so on.
