  C-type lectins are a superfamily of Ca2+ dependent carbohydrate-recognition proteins which play significant diverse roles in nonself-recognition and clearance of invaders.Recent studies have clarified the significant roles of C-type lectins in vertebrates.However, study on the immune responses mediated by invertebrates C-type lectin and relative mechanism is still in its infancy.Here, a C-type lectin (CfLec-3) from Zhikong scallop Chlamysfarreri, with three carbohydrate-recognition domains (CRDs), was selected to dissect its functions in innate immunity and the binding mechanism towards pathogen associated molecular patterns (PAMPs).CfLec-3 protein exhibited a broad tissue distribution including hepatopancreas, gill,kidney, mantle and muscle of the scallop.Expression of CfLec-3 mRNA in hemocytes was significantly (P<0.01) up-regulated after stimulation of LPS, PGN or β-glucan.
