Abstract
The nucleotide sequence of a cDNA clone of winter flounder antifreeze protein was determined by the dideoxynucleotide method. The sequence would predict a protein of 91 amino acids composed of a prepropeptide of 38 amino acids and a mature protein of 53 amino acids, which includes four complete 11-amino acid repeats. This predicted sequence corresponds to an antifreeze protein of intermediate size which is one 11-amino acid repeat longer than the smallest anti-freeze proteins found in the serum of winter flounder during the cold season. Southern blot hybridization analysis of winter flounder genomic DNA with radioactive cDNA probes reveals a multigene family of potential antifreeze protein genes. This conclusion is supported by amino acid sequence analysis of several serum antifreeze proteins.
