Characterization and expression analysis of chymotrypsin after bacterial challenge in the mud crab, Scylla paramamosain

Chymotrypsin is one of the serine proteases families that have various biological functions. A chymotrypsin gene was isolated from hepatopancreas of the mud crab, Scylla paramamosain (designated SpCHY) in this study. The full-length cDNA of SpCHY contained 942 nucleotides with a polyadenylation sequence and encoded a peptide of 270 amino acids with a signal peptide of 17 amino acids. The SpCHY ...

Characterization and expression analysis of the prophenoloxidase activating factor from the mud crab Scylla paramamosain.

Prophenoloxidase activating factors (PPAFs) are a group of clip domain serine proteinases that can convert prophenoloxidase (pro-PO) to the active form of phenoloxidase (PO), causing melanization of pathogens. Here, two full-length PPAF cDNAs from Scylla paramamosain (SpPPAF1 and SpPPAF2) were cloned and characterized. The full-length SpPPAF1 cDNA was 1677 bp in length, including a 5'-untransla...

Identification, Characterization, and Functional Analysis of Tube and Pelle Homologs in the Mud Crab Scylla paramamosain

Tube and Pelle are essential components in Drosophila Toll signaling pathway. In this study, we characterized a pair of crustacean homologs of Tube and Pelle in Scylla paramamosain, namely, SpTube and SpPelle, and analyzed their immune functions. The full-length cDNA of SpTube had 2052 bp with a 1578 bp open reading frame (ORF) encoding a protein with 525 aa. A death domain (DD) and a kinase do...

Rapid isolation and characterization of polymorphic microsatellite loci in the mud crab, Scylla paramamosain (Portunidae).

Scylla paramamosain is a widespread and commercially important species of coastal marine crab. We identified 13 polymorphic microsatellite loci from a genome library constructed with 5'-anchored PCR method. Thirty-two S. paramamosain from the East China Sea were used to analyze the characteristics of these loci. The number of alleles per locus ranged from 3 to 8, with a mean of 5.923. Observed ...

Cloning and characterization of the SpLRR cDNA from green mud crab, Scylla paramamosain.

Infectious diseases have seriously inhibited the aquaculture of mud crab Scylla paramamosain in southeastern China. Identification of the immune molecules and characterization of the defense mechanisms will be pivotal to the reduction of these diseases. Available data show that leucine-rich repeat (LRR) proteins play a crucial role in protein-protein interactions, recognition processes or immun...
