CC -!- FUNCTION: Contributes to protect fish blood from freezing at subzero
CC sea water temperatures. Lowers the blood freezing point. Binds to
CC nascent ice crystals and prevents further growth (By similarity).
CC {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Secreted {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the type-III AFP family. {ECO:0000305}.
