... role of CLCN5 under low-salinity stress, a cDNA sequence of CLCN5 (TrCLCN5) was cloned from Takifugu rubripes using the reverse transcription PCR (RT-PCR) technique. The results showed that TrCLCN5 cDNA contained a complete open reading frame of 2505 bp continuously encoding 834 amino acid residues. Sequence alignments revealed that the TrCLCN5 cDNA is highly homologous (96.2% and 96.1%) with that of Takifugu bimaculatus and Takifugu flavidus. SignalP and TMH...
