INP_RC-mSA2 generator

This part contains the INPRC-mSA2 fusion protein controlled by a weak to medium constitutive promoter and RBS.

Usage and Biology

INPRC is a truncated Ice Nucleating Protein from which the N-terminal domain has been removed. The truncated INP is still capable of catalysing the formation of ice crystals, but is no longer localised to the outer cell membrane.[1] The mSA2 protein has been fused to INPRC for use in protein adhesion experiments performed by the UGent Belgium 2016 iGEM team. MSA2 is a monomeric variant of streptavidin that retains the biotin-binding capabilities and is better suited for protein fusions since it is less likely to cause aggregation.[2]


When crude cell lysate of a culture of E. coli expressing mGFPuv2 is added to supercooled water, no reaction takes place. When crude cell lysate containing INP_RC-mSA2 is added, ice is formed instantly. This demonstrates that the cytoplasmatic INP_RC fusion protein is still active as an ice nucleating protein.
