| Protein existence | Evidence at protein level. |
General annotation (Comments)
| Function | Ice nucleation proteins enable bacteria to nucleate crystallization in supercooled water. |
| Subcellular location | |
| Domain | Contains 122 imperfect repeats of a consensus octapeptide A-G-Y-G-S-T-L-T; further on a 16-residue and a regional 48-residue periodicity is superimposed. |
| Biotechnological use | Used by snowmaking industry to promote ice nucleation for artificial snow and economize water. Sold under the name Snomax by York. |
| Miscellaneous | A structural model is suggested in which the ice nucleation protein displays a symmetry related to that of ice. |
| Sequence similarities | Belongs to the bacterial ice nucleation protein family. |
