The receptor for the globular heads of C1q, C1qBP/gC1qR/p33, is a multicompartmental, multifunctional cellular protein with an important role in infection and in inflammation. In the present study, we identified and characterized the complement component 1q subcomponent binding protein (C1qBP) from the tiger shrimp Penaeus monodon (designated as PmC1qBP).(More)
MAPK kinase 1 interacting protein 1 (MAP2K1ip1) is an important scaffold proteins of the mitogen-activated protein kinase (MAPK) pathway that form an active signaling module and enhance the specificity and spatiality of MAPK signaling. In the present study, we identified and characterized a MAP2K1ip1 cDNA from tiger shrimp Penaeus monodon (designated as(More)
Argonaute2 binds to a short guide RNA (microRNA or short interfering RNA) and guides RNAs direct RISC to complementary mRNAs that are targets for RISC-mediated gene silencing. Here we identified and characterized Argonaute2 from black tiger shrimp Penaeus monodon (designated as PmAgo2). The full-length cDNA of PmAgo2 contained a 5' untranslated region (UTR)(More)
It is widely accepted that protein phosphorylation is a major control event in regulating cell cycle. In the present study, a novel M-phase phosphoprotein 6 (MPP6) was identified from black tiger shrimp Penaeus monodon (designated as PmMPP6) by cDNA library and RACE approaches. The full-length cDNA of PmMPP6 was of 690 bp, including a 5′-terminal(More)
The transactivation response RNA-binding protein (TRBP) interacts with Dicer and binds to double-stranded RNA as a critical component of the RNA-induced silencing complex, which is a key complex in the RNA interference pathway. The full-length cDNA of TRBP from the tiger prawn, Penaeus monodon, (PmTRBP; 1548 bp long with a 1029 bp coding region) was(More)
Dicer is a key initiative protein of the RNA interference (RNAi) pathway that produces small interfering RNAs (siRNAs) or micro RNAs (miRNA), which then leads to RNA-directed gene regulation or viral immunity. In the present study, we identified and characterized a Dicer2 cDNA from black tiger shrimp Penaeus monodon (designated as PmDcr2). The full length(More)
Chitinases are crucial enzymes for crustaceans. Previous researches had already revealed that chitinases play important roles in digestion, molting and defense against viruses. In the present study, a chitinase cDNA was identified from black tiger shrimp (Penaeus monodon) and designated as PmChi-5. The full-length PmChi-5 cDNA was 2860 bp in size,(More)
Chitinase is a multi-gene family, which play important physiological roles in crustaceans, involved in several biological processes, including digestion, molting and defense against viruses. In the present study, a chitinase-4 gene (PmChi-4) was cloned from Penaeus monodon by rapid amplification of cDNA ends (RACE). The full length of PmChi-4 cDNA was 2178(More)
This article reports on the changes in the metabolic detoxification indices of the hepatopancreas, muscle, and gill tissues of juvenile prawn (body length of 5.0 ± 0.5 cm) of Penaeus monodon at different ammonia levels (at concentrations of 0, 10, 20, and 30 mg/L) as well as the immune-related gene expressions of the prawn under elevated ammonia (30 mg/L)(More)
Carbohydrate structures on the cell surface encode complex information that through specific recognition by carbohydrate-binding proteins (lectins) modulates interactions between cells, cells and the extracellular matrix, or mediates recognition of potential microbial pathogens. Galectins are a family of ß-galactoside-binding lectins, which are evolutionary(More)
