Recombinant production and characterization of the carbohydrate recognition domain from Atlantic salmon C-type lectin receptor C (SCLRC)
The Atlantic salmon C-type lectin receptor C (SCLRC) locus encodes a potential oligomeric type II receptor. C-type lectins recognize carbohydrates in a Ca2+-dependent manner through structurally conserved, yet functionally diverse, C-type lectin-like domains (CTLDs). Many conserved amino acids in an...

The Atlantic salmon C-type lectin receptor C (SCLRC) locus encodes a potential oligomeric type II receptor.
