The nucleic acid binding protein PcCNBP is transcriptionally regulated during the immune response in red swamp crayfish Procambarus clarkii

Cellular nucleic acid binding proteins (CNBPs) represent a highly conserved protein family among vertebrates; they harbour seven tandem zinc finger repeats CCHC type and have been described as transcriptional and translational regulators. To date, there is little characterization of CNBP in invertebrates since its structure and function have been analysed solely in Drosophila melanogaster. However, no CNBP has been investigated in other arthropod systems. In an effort to isolate immune-related genes in Procambarus clarkii, a partial mRNA coding a zinc finger containing protein was found to be up-regulated during the response to white spot syndrome virus (WSSV) infection. The red swamp crayf…
