The cloned cDNAs encoding snakehead PRLR (shPRLR) from the gill was determined its
nucleotide and deduced amino acid sequence. The conserve structural features of shPRLR show
a common to the member of the class I cytokine receptor superfamily, such as two pairs of
cysteine residues, a WSXWS motif, a single transmembrane domain with the box 1 and box 2. The
shPRLR mRNA showed highest expression in gill and kidney. Furthermore, shPRLR levels in gills
of snakeheads were not significant difference between fresh water and 10% NaCl-dissolved water.
