| contents | Genomic insights into fibrinogen-related proteins and expression analysis in the Pacific white shrimp, Litopenaeusvannamei. Hao, Qiang Gao, Xiuyan Sun, Mingzhe Liu, Yuan Animals Penaeidae Arthropod Proteins Phylogeny Immunity, Innate Fibrinogen Gene Expression Profiling Amino Acid Sequence Gene Expression Regulation Sequence Alignment Fibrinogen-related domain (FReD) containing proteins are an evolutionarily conserved immune gene family characterized by the C-terminal fibrinogen (FBG) and diverse N-terminal domains. To understand the complexity of this family in crustaceans, we performed genome screening and identified 43 full-length FReDs encoding genes in Litopenaeus vannamei. Structural classification analysis revealed these putative FReDs could be divided into six types, including two reported types (LvFReDI and II) and four new types (LvFReDIII-VI). Sequence and phylogenetic analysis showed that FBG domains were highly conserved throughout and phylogeny clusters correlated strongly with gene type. We analyzed the temporal and spatial expression patterns of LvFReD genes based on the transcriptomes of developmental stages, adult tissues or pathogen infected tissues of L. vannamei. Most LvFReDs were expressed from larval in membrane stage, and exhibited tissue-specific expression patterns and immune-responsive transcription after challenge with bacteria or virus. Further time-course expression analysis suggested that LvFReDII genes with additional coiled-coil region were more sensitive to pathogens than LvFReDI genes. Our findings provided comprehensive gene sequence resources and expression profiles of FReD genes in shrimp, which give insights into clarifying the diversity and function of these genes in crustaceans. |
