Prophenoloxidase (proPO) is a conserved copper-containing enzyme that plays important roles in immune response of crustaceans and insects. In the present study, the full-length cDNA of a prophenoloxidase (designated EsproPO) was cloned from haemocytes of Chinese mitten crab Eriocheir sinensis by expressed sequence tag (EST) and PCR techniques. The isolated(More)
Crustin is a cysteine-rich antibacterial peptide which widely distributes within decapod crustaceans. In the present study, the cDNA encoding crustin-like peptide (designated CrusEs) was cloned from Chinese mitten crab Eriocheir sinensis by using rapid amplification of cDNA ends (RACE) approaches and expressed sequence tag analysis. The full-length cDNA of(More)
The pacifastin family, characterized by several conserved arrays of six cysteine residues, is a newly identified serine protease inhibitor (SPI) family discovered uniquely in arthropods and plays important roles in multiple biological processes. In the present study, the full-length cDNA of a pacifastin light chain (designated ESPLC) was cloned from the(More)
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 708bp, encoding a typical long form carbohydrate-recognition domain of 130 residues. The deduced amino(More)
Cyclophilin A (CypA), a receptor for the immunosuppressive agent cyclosporin A (CsA), is a cis–trans peptidyl-prolyl isomerase (PPIase) which accelerates the cis–trans isomerization of prolyl-peptide bonds, interacts with a variety of proteins and therefore regulates their activities. One CypA (designated CfCypA) cDNA was cloned from Chlamys farreri by(More)
Double-stranded RNA (dsRNA) is a virus-associated molecular pattern which induces antiviral innate immune responses and RNA interference (RNAi) in mammals. In invertebrates, RNAi phenomenon has been widely studied, but dsRNA-induced innate immune response is seldom reported. In the present study, two different dsRNAs specific for green fluorescent protein(More)
Antimicrobial peptides are important effectors in the host innate immune response against microbial invasion. In the present study, the cDNA encoding a crustin (designated CrusEs2) was cloned from Chinese mitten crab Eriocheir sinensis by using EST analysis and rapid amplification of cDNA ends (RACE) approach. The full-length cDNA of CrusEs2 was of 1237 bp,(More)
Serine proteinase inhibitors (SPIs) play important roles in host physiological and immunological processes in all multicellular organisms. A novel Kazal-type SPI gene was cloned from the Zhikong scallop Chlamys farreri (designated as CfKZSPI) by expressed sequence tag (EST) and rapid amplification of cDNA ends (RACE) approaches. The full-length cDNA of(More)
