Classification of the multigene family of fatty acid binding proteins (FABPS) and transcription profile of the genes in striped cateish (Pangasianodon hypophthalmus)

Abstract

Striped catfish (Pangasianadon hypophthalmus) is an economically important fish in Vietnam. The eatfish fillets contain high fatty acid composition. The FABP family is involved in lipid transport and metabolism as well as in the regulation of gene expression and cell development. In this study, the catfish genome database was searched for fabp gene family; then, gene structure, classification and phylogenetic relationships were analyzed. In striped catfish genome, we found 10 fabp genes that are homologous to other fish species and other 5 novel fabp genes that have not been clearly annotated. These newly identified fabp genes cluster separately from the known menibers of the fabp family on the phylogenetic tree, and further studies are needed to understand their roles and functions. The results of this study provide a resource for further research on the function of fabp genes and their genetic diversity in striped catfish.
