Abstract

Abstract: In order to clarify the effect of Flotillin 2 (FLOT2) gene on the reproductive performance of buffalo, buffalo FLOT2 gene was cloned and analyzed by bioinformatics.FLOT2 was cloned by PCR, cloned and sequenced, then its protein structure was predicted and analyzed by bioinformatics tools.The results showed that the coding region of buffalo FLOT2 gene was 1 287 bp, 3'UTR was 277 bp, encoded 428 amino acids.The buffalo FLOT2 gene shared 98%, 98%, 97%, 90%, 93%, 92% and 92% of similar nucleotide sequence with that of Bos taurus, Ovis aries, Capra hircus, Mus musculus, Equus caballus, Felis catus and Homo sapiens, respectively.Phylogenetic tree analysis showed that FLOT2 gene was highly conserved in different species and evolution.FLOT2 protein was weakly acidic, without signal peptide, located in the cytoplasmic, and with the presence of SPFH_flotillin and SPFH_hflk domain.microRNA prediction showed bta-miR-2438, bta-miR-2379 and bta-miR-1777a maybe target the 3'UTR of buffalo FLOT2.In a word, this study provided an important reference for surveying the regulation mechanism of FLOT2 gene in buffalo reproductive performance, especially, during buffalo gametogenesis and embryogenesis.
