title: Molecular cloning and expression analysis of the Ajuba gene of grass carp (Ctenopharyngodon idella) involved in cellular response to viral infection.
abstract: Ajuba belongs to the LIM domain proteins, which are involved in the assembly of the extracellular matrix and, along with associated proteins, regulate target genes that connect the extracellular matrix and the cytoskeleton. In the present study, we characterized the entire cDNA sequence of the Ajuba gene from grass carp (gcAjuba). The gcAjuba cDNA contained an open reading frame (ORF) of 2121 bp encoding a polypeptide of 706 amino acids with an estimated molecular mass of 75.966 kDa and three LIM domains in the C-terminal. The transcriptional level of gcAjuba was significantly up-regulated following the stimulation of virus in vitro. Sub-cellular location of gcAjuba and GCRV-JX01 NS26 proteins did not overlap in the cytoplasm and no direct interaction between gcAjuba and the protein NS26 was detected by co-immunoprecipitation (CO-IP) test in grass carp kidney cells. Based on these results, the gcAjuba is determined to be an immediately inducible gene responding to viral infection and in vivo association of gcAjuba with NS26 could not be confirmed, which has been suggested by yeast two-hybrid assay in previous report.
