ABSTRACT: We report the isolation and characterization of products from a subtractive cDNA library from the haemolymph of Penaeus monodon experimentally infected with white spot syndrome virus (WSSV). One cDNA derived from up-regulated mRNA was identified. A homology search indicated similarity to the putative protein syntenin (TE8). The nearly complete nucleotide sequence of TE8 was obtained by rapid amplification of cDNA (RACE). Its putative protein product contained a tandem repeat of PDZ domains (postsynaptic density protein or PSD-95, DlgA and ZO-1). We propose that TE8 may function as an adapter that couples PDZ-binding protein(s) in a signaling pathway involved in the shrimp response to WSSV.
