Molecular cloning and mRNA expression of cyclophilin A gene in black tiger shrimp (Penaeus monodon).
The techniques of homology cloning and anchored PCR were used to clone the cyclophilin A (CypA) gene from black tiger shrimp (Penaeus monodon). The full-length cDNA of black tiger shrimp CypA (btsCypA) contained a 5' untranslated region (UTR) of 81 bp, an ORF (open reading frame) of 495 bp encoding a polypeptide of 164 amino acids with an estimated molecular mass of 17.68 kDa and a 3' UTR of 308 bp. The predicted amino acid sequence of btsCypA shared high identity with CypA in other organisms. A quantitative reverse transcriptase Real-Time PCR (qRT-PCR) assay was developed to assess the mRNA expression of btsCypA in different tissues and the temporal expression of btsCypA in the hepatopancreas challenged by lipopolyssacharide (LPS). Higher-level mRNA expression of btsCypA was detected in the tissues of hepatopancreas and blood. The expression of btsCypA in the hepatopancreas was up regulated after stimulated by LPS. The results indicated that btsCypA was a constitutive and inducible expressed protein and could be induced by LPS.
