Abstract: To clone the Yemule aries inhibin α (INHα) subunit gene and express its recombinant protein,total RNA was extracted from Yemule aries ovary tissue by Trizol,and a pair of primer was designed according to the published aries INHα subunit gene sequence (GenBank No.XM_004004955.1). INHα subunit gene coding sequence was amplified by RT-PCR.The mature peptide cDNA was further amplified and cloned into the Scal Ⅰ and EcoR Ⅰ sites of the pEGFP-N1 expressing vector to generate the recombinant plasmid pEGFP-INHα.The plasmid was transformed into DH5α,after appraisal,sequencing,proves that successful build INHα subunit gene eukaryotic expression vector.The sequence result was compared with homologous sequences from animals including human,gorilla,cow and other animals alpha subunit of INHα subunit gene sequence homology comparison analysis.Sequence alignment showed that ranks of their similarities were above 50%,proved that INHα subunit gene was highly conservative.By RT-PCR and Western blotting method verified the eukaryotic expression vector of statin INHα subunit gene expression and protein expression of success in BHK cells.
