英文摘要Lectins are a family of carbohydrate-recognition proteins which play crucial roles in innate immunity. In this study, a new lectin (CfLec-2) gene was cloned from Chlamys farreri by EST and RACE approaches. The full-length cDNA of CfLec-2 was composed of 708 bp, encoding a typical Long form carbohydrate-recognition domain of 130 residues. The deduced amino acid sequence showed high similarity to Brevican in Homo sapiens, C-type lectin-1 and lectin-2 in Anguilla japonica. The cDNA fragment encoding the mature peptide of CfLec-2 was recombined into plasmid pET-32a (+) and expressed in Escherichia coli Rosseta-Gami (DE3). The recombinant CfLec-2 (rCfLec-2) protein exhibited aggregative activity toward Staphylococcus haemolyticus, and the agglutination could be inhibited by D-mannose but not EDTA or D-galactose, indicating that CfLec-2 was a Ca2+ independent lectin. Moreover, rCfLec-2 could suppress the growth of E. coli TOP10F'. These results suggested that CfLec-2 was perhaps involved in the recognition and clearance of bacterial. pathogens in scallop.
