| Function: | |
Binds to the surface of ice crystals (Ref.1, PubMed:20030710, PubMed:27613857). Inhibits growth of the ice crystals (PubMed:20030710). Has antifreeze activity for survival under snow cover. Has high thermal hysteresis (TH) activity, which is the ability to lower the freezing point of an aqueous solution below its melting point, and thus the freezing of the cell fluid can be prevented protecting the organism from ice damage (PubMed:20030710, PubMed:27613857). The TH activity of this protein is 2.0 degrees Celsius at 0.11 mM (PubMed:27613857). {ECO:0000269|PubMed:20030710, ECO:0000269|PubMed:27613857, ECO:0000269|Ref.1}. |
