Table 1.

Characteristics of Toll-like receptors (TLRs) of brown trout used in the present study. The chromosome number, location, transcriptional direction (F–forward and R–reverse), NCBI accession numbers, length of mRNA, and the amino acid sequences of each TLR are provided. The details of the predicted isoelectric point (pI), molecular weight (MW), and subcellular location are also shown.

* Unlike higher vertebrates, bony fish do not have TLR6 and TLR12 [36,37,38]. Based on our local synteny analysis, the accession numbers of the originally described TLR6 and TLR12 were re-annotated as TLR1 and TLR19, respectively.
