Ice nucleation protein (INP) is a protein found in ''Xanthomonas campestris'' pc. ''campestris'' BCRC 12846. It functions as, as its namesake suggests, causing ice nucleation and formation.

The INP protein is composed of a N-terminal region that appears to interact with the phospholipid membrane, a C-terminus hydrophillic region that is exposed to the outside membrane, as well as a central 8, 16, or 48 amino acid motif that is responsible for INP's ice nucleation properties.

Usage and Biology

Ice nucleation protein (INP) is a protein found in Xanthomonas campestris pc. campestris BCRC 12846. It functions as, as its namesake suggests, causing ice nucleation and formation. However, recent studies have utilized INP for its surface display properties. In nature, the protein is anchored in the membrane through a glycosylphosphatidylinositol (GPI) anchor, a relatively rare occurance in prokaryotes.

The INP protein is composed of a N-terminal region that appears to interact with the phospholipid membrane, a C-terminus hydrophillic region that is exposed to the outside membrane, as well as a central 8, 16, or 48 amino acid motif that is responsible for INP's ice nucleation properties. However, this central amino acid motif is not necessary for INP's surface display properties. Therefore, scientists truncated the protein, retaining only the N (179 aa) and C termini (49 aa) to produce INPNC.

This truncated protein retains INP's membrane display abilities, and also contains a GS amino acid linker followed by a site containing multiple restriction sites for the easy ligation of additional DNA for INPNC fusion experiments and surface display of desired proteins.
