Cloning and characterization of the Atlantic salmon serum lectin, a long-form C-type lectin expressed in kidney
We report the cloning of four distinct cDNAs and a genomic sequence encoding a multimeric serum lectin found in the blood of Atlantic salmon (Salmo salar). The sequence variation among the cDNAs as well as genomic Southern blotting analysis revealed a multi-gene family. Expression of the salmon seru...

Summary: | We report the cloning of four distinct cDNAs and a genomic sequence encoding a multimeric serum lectin found in the blood of Atlantic salmon (Salmo salar). The sequence variation among the cDNAs as well as genomic Southern blotting analysis revealed a multi-gene family. Expression of the salmon serum lectin (SSL) was specific to kidney, as demonstrated by RT-PCR. Analysis of the 173-amino acid sequence of SSL confirmed that it is a member of the C-type lectin superfamily. Sequence alignments and intron/exon structure of the SSL gene showed it to belong to the type VII C-type lectins, which normally bind to galactose or other ligands, whereas the SSL protein sequence contains the EPN motif of mannose-binding C-type lectins, that bind mannose or related carbohydrates.
