Cloning and characterization of a shrimp clip domain serine protease homolog (c-SPH) as a cell adhesion molecule

Identification of three different types of serine proteases (one SP and two SPHs) in Chinese white shrimp

“…P. monodon SPH was also down-regulated by yellow head virus (YHV) challenge [25]. Although masquerade has been reported to be involved in prophenoloxidase activation [11] and has been identified as a cell adhesion molecule [27], it has also been identified as a binding protein of YHV [25] and a pattern recognition receptor (PPR) [13]. Therefore, it could be speculated that FcMas might also function as a PPR.…”

Molecular cloning, characterization and expression of a masquerade-like serine proteinase homologue from black tiger shrimp Penaeus monodon

“…A cDNA encoding a PPAF has been cloned from the hypodermal tissue of the blue crab, Callinectes sapidus [3] whereas a cDNA encoding a pseudo-clip SPH of kuruma shrimp Marsupenaeus japonicus has been reported and characterized from the mRNA expression [19]. Recently, a shrimp clip domain serine protease homologue (c-SPH) of P. monodon has been reported as a cell adhesion molecule [20]. However, the molecular mechanism(s) by which crustacean serine proteinase homologues are involved in the regulation of the prophenoloxidase system is yet to be clarified.…”

Bacillus NP5 Improves Growth Performance and Resistance Against Infectious Myonecrosis Virus in White Shrimp (Litopenaeus vannamei) (Bacillus NP5 Meningkatkan Pertumbuhan dan Ketahanan Terhadap Infeksi Virus Myonecrosis pada Udang Putih (L. vannamei)

“…anticoagulant proteins, aglutinins, PO enzymes, antimicrobial peptides, and protease inhibitors (Jiravanichpaisal et al, 2006). The infecting virus causes the host cells to modify; making them identifiable by the haemocyte as modified cells or foreign cells which would be digested or destroyed by the haemocytes (Lin et al, 2006). Probiotic administered in this study was live bacteria which have cell wall components such as peptidoglycan (PG), Lipopolysaccharides (LPS), and β-glucans (BGs); they are recognized as foreign materials and will activate several immune molecules into haemolymph, in which immune molecules are produced and stored in the granules of haemocytes (Sritunyalucksana and Söderhäll, 2000).…”
