Fig. 1. Nucleotide and predicted amino acid sequence of Atlantic cod PepT1 (codPepT1). The numbers on the right refer to positions of the nucleotides (lower row) and amino acids (upper row). The stop codon is indicated by ^***. A polyadenylation signal is underlined. Positions for degenerated (broken underline) and species specific (solid underline and double underline) primers are indicated in the nucleotide sequence. In the amino acid sequence, putative transmembrane domains are underlined in red and named I to XII. Potential extracellular N-glycosylation sites (dark green boxed areas) and potential cAMP/cGMP-dependent protein kinase phosphorylation sites at the cytoplasmic surface (light grey boxed areas) are indicated.
